Calculate the length of the unknown side of this right-angled triangle.
9 cm
8 cm

Answers

Answer:

the length of the unknown side of the right angle triangle is 1 cm

Step-by-step explanation:

The computation of the length of the unknown side of the right angle triangle is shown below:

= √9^2 - √8^2

= √81 - √64

= 9 - 8

= 1 cm

Hence, the length of the unknown side of the right angle triangle is 1 cm

What is the Rotational speed of someone standing in Helsinki, Finland located at 60°11' N and 24°56' E.? (radius of the earth is 3960 miles)

Answers

Answer:

515.5 mph

Step-by-step explanation:

I am fairly confident we are taking the same test/quiz thing right now and I figured this one out so here ya go:

60 degrees + 11 sec = 60.183 degrees

3960 * cos(60.183) = 1969 some number in relation to the distance to the poles

2 * pi * 1969 = 12371.8

12371.8 / 24 = 515.5mph

look up "How to Calculate Rotational Speed Around Earths Axis" on YT, video is by " VAM! Physics & Engineering" that is where I found the formula stuffs

A girl is on the beach and the angle of elevation from her feet to the top of a lighthouse is 62' If the lighthouse is 30ft tall, how far away is the girl from the lighthouse? Please show

your work!

I need help plssss

Answers

Answer:

15.95 feets

Step-by-step explanation:

Given that:

Angle of elevation = 62°

Using trigonometric relation :

Tanθ = opposite / Adjacent

From the drawing attached :

Opposite = 30 feets

Distance between girl and lighthouse = d

Tan 62 = 30 / d

1.8807264 * d = 30

d = 30 / 1.8807264

d = 15.951283

d = 15.95 feets

In triangle ABC, the measure of angle CAB is 80° and the measure of angle ABC is 45.5°. What is the measure of angle BCA in degrees? A 125.5°125.5 degrees B 54.5°54.5 degrees C 55.5°55.5 degrees D 64.5°

Answers

Answer:

B 54.5°

Step-by-step explanation:

Since we have a triangle,

CAB + ABC + BCA = 180 (sum of angles in a triangle)

Since CAB = 80° and ABC = 45.5°, substituting these into the equation, we have

80° + 45.5° + BCA = 180°

simplifying, we have

125.5° + BCA = 180°

collecting like terms, we have

BCA = 180° - 125.5°

BCA = 54.5°

So, the answer is B

So you will do 35=21 to the power x +x

So after you do it it will be

X=441 -35 it will be 406 and after you finish you will do it in the calculator so

The Answer is : 20.15

Theres an easier way. Pythagorean theorem-
A^2+B^2=C^2
A and B are legs while C is the hypotenuse or slanted one.
So rearrange formula.
C^2 - A^2=B^2
1225 - 441 = B^2

3x+30=180 degrees, what is the value of the letter x in this problem?

Answers

Answer:

Step-by-step explanation:

180-30=150/3=50

3x + 30 = 180

-30 -30 subtract 30 on both sides, solve for 180 - 30 which is 150.

___________

3x = 150

__ ___ divide 3 on both sides, solve for 150 ÷ 3 which is 50.

x = 50, final answer

Step-by-step explanation:

Pythagoras is the sum of the square of two sides is equal to the square of the longest side. Then Alma is going to walk through the park from Point A to Point B is 282.84 ft.

What is a right-angle triangle?

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.

A right-angle triangle has sides with lengths 200 ft and 200 ft.

By Pythagoras theorem, we have

H² = P² + B²

H² = 200² + 200²

H² = 40000 + 40000

H² = 80000

H = 200√2

H = 282.84 ft

Alma is going to walk through the park from Point A to Point B is 282.84 ft.

The function y = -16t+^2 40 represents the height y (in feet) of a water droplet t seconds after falling from an icicle. After how many seconds does the water droplet hit the ground? Round your answer to two decimal places.

Answers

Answer:

The water droplet will hit the ground 1.58 seconds after it started falling.

Step-by-step explanation:

The function:

y = -16*t^2 + 40

represents the height of a water droplet t seconds after falling from an icicle.

We want to find the value of t such that the water droplet hits the ground, and this will happen when y = 0.

Then we only need to solve the equation:

0 = y = -16*t^2 + 40

0 = -16*t^2 + 40

16*t^2 = 40

t^2 = 40/16

t = √(40/16) = 1.58

The water droplet will hit the ground 1.58 seconds after it started falling.

Segments AB,DC, and EC intersect at point C. Angle DCE measures 148. Find the value

Answers

Answer:

x = 16°

Step-by-step explanation:

We can see that AB is a straight line. The sum of angles on a straight line adds up to 180°

∠ACD + ∠DCE + ∠ECD = 180° (sum of angles on a straight line)

∠ACD = x, ∠DCE = 148, ∠ECD = x

substituting the respected values for the angles gives:

x + 148 + x = 180

2x + 148 = 180

subtracting 148 from both sides:

2x + 148 - 148 = 180 - 148

2x = 32

Dividing both sides by 2, to get x:

2x/2 = 32/2

x = 16°

John took a taxi from his house to the airport. The taxi company charged a pick-up fee of $4.70 plus $2.50 per mile. The total fare was $24.70, not including the tip. How many miles was the taxi ride?

Answers

Answer:

Step-by-step explanation:

You can solve this by creating a linear equation.

Slope: 2.50

Y-intercept: 4.70

y=2.50x+4.70

Since we know that the total fare was 24.70 we can plug it into the y.

24.70=2.50x+4.70

Now solve for the equation.

20=2.50x

8=x

So he went 8 miles with the taxi.

Total number or mile taxi run is 8 miles.

Given that;

Pick up charge = $4.7

Charges per mile = $2.5 per mile

Total fare = $24.7

Find:

Number of mile taxi ride

Computation:

Total fare = Pick up charge + [Total number or mile taxi run][Charges per mile]

24.7 = 4.7 + [Total number or mile taxi run][2.5]

[Total number or mile taxi run][2.5] = 24.7 - 4.7

[Total number or mile taxi run][2.5] = 20

Total number or mile taxi run = 20 / 2.5

Total number or mile taxi run = 8 miles

When the two boys were going to high school, Ernest often came over in the evening to study with Claude, and while they worked at the long kitchen table Mrs. Wheeler brought her darning and sat near them, helping them with their Latin and algebra. Even old Mahailey was enlightened by their words of wisdom.Mrs. Wheeler said she would never forget the night Ernest arrived from the Old Country. His brother, Joe Havel, had gone to Frankfort to meet him, and was to stop on the way home and leave some groceries for the Wheelers. The train from the east was late; it was ten o'clock that night when Mrs. Wheeler, waiting in the kitchen, heard Havel's wagon rumble across the little bridge over Lovely Creek. She opened the outside door, and presently Joe came in with a bucket of salt fish in one hand and a sack of flour on his shoulder. While he took the fish down to the cellar for her, another figure appeared in the doorway; a young boy, short, stooped, with a flat cap on his head and a great oilcloth valise, such as pedlars carry, strapped to his back. He had fallen asleep in the wagon, and on waking and finding his brother gone, he had supposed they were at home and scrambled for his pack. He stood in the doorway, blinking his eyes at the light, looking astonished but eager to do whatever was required of him. What if one of her own boys, Mrs. Wheeler thought. . . . She went up to him and put her arm around him, laughing a little and saying in her quiet voice, just as if he could understand her, "Why, you're only a little boy after all, aren't you?"Ernest said afterwards that it was his first welcome to this country, though he had travelled so far, and had been pushed and hauled and shouted at for so many days, he had lost count of them. That night he and Claude only shook hands and looked at each other suspiciously, but ever since they had been good friends.
