Find The Length Of The Third Side. If Necessary, Write In Simplest Radicalform.4729

Answers

Answer 1

Answer:

7

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

let the third side be x , then

x² + (4[tex]\sqrt{2}[/tex] )² = 9²

x² + 32 = 81 ( subtract 32 from both sides )

x² = 49 ( take the square root of both sides )

x = [tex]\sqrt{49}[/tex] = 7

Then the third side is 7

The piper family arrived at the campground at the time shown on the clock. I took the family 2 hours and 15 minutes to get to the campground. What time did the family leave their house?

Answers

Answer:

As you included no picture, I do not know the time on the clock. We can however, work with assumed figures which you can then relate to your question.

Assuming the time on the clock was 10:45 am, if the family took 2 hours and 15 minutes to get to the camp ground, simply subtract this from 10:45 to find out what time they arrived.

Subtract the 2 hours from 10am:

= 10 - 2

= 8am

Subtract the 15 minutes from 45:

= 45 - 15

= 30

Put that together:

= 8:30 am

They left their house at 8:30 am using this scenario.

You start at (6, 7). You move right 3 units. Where do you end?

Answers

Answer:

(9, 7) is where you would end

Step-by-step explanation:

We know that;

x-value = 6

y-value = 7

We also know that by moving 3 units right u will add 3 to the x-value, therefore;

Final x-value = 6 + 3 = 9

Final y-value = 7 (there is no change)

Final coordinates: (9, 7)

Answer:

[tex]l = 3.66[/tex]

Step-by-step explanation:

Given

[tex]r =1[/tex]

[tex]\theta = \frac{7\pi}{6}[/tex]

Required

The arc length (l)

This is calculated as:

[tex]l= r\theta[/tex]

So, we have:

[tex]l = 1 * \frac{7\pi}{6}[/tex]

[tex]l = \frac{7\pi}{6}[/tex]

So, we have:

[tex]l = \frac{7*3.14}{6}[/tex]

[tex]l = 3.66[/tex]

∠E and ∠F are vertical angles. If m∠E=(5x+55)° and m∠F=(11x-53)°, find m∠E

Answers

Answer:

145° = m∠E

Step-by-step explanation:

Vertical Angles: always congruent, therefore, to find Angle E first find "x" ;

5x + 55 = 11x - 53

55 = 6x - 53

108 = 6x

108/6 = x

18 = x

Now that we know x-value is 18, u can substitute that in for the equation for Angle E for "x";

=> 5(18) + 55 = m∠E

=> 145° = m∠E

What is the distance to the nearest tenth of a unit between point H ( -4,6 ) and point I ( 2,-3 )

Answers

Answer:

10.81 units

Step-by-step explanation:

Given data

point H ( -4,6 ) and point I ( 2,-3 )

x1= -4

y1=6

x2= 2

y2=-3

The formula for the distance between two points is

d=√((x_2-x_1)²+(y_2-y_1)²)

d=√((2-(-4))²+(-3-6)²)

d= √(2+4)²+(-9)²)

d= √(6)²+(-9)²)

d= √36+81

d=√117

d= 10.81 units

Hence the distance between the points is 10.81 units
