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.

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

36-4+1         32+1     31

i hope this helps you!

Answer:

The answer is 9.

Step-by-step explanation:

Hey there, so it looks to me that you just have to subsitute 2 in for x, and solve the equation. Like this.

1. Plug in X: 3(2)^2 -2(2) + 1

2. Solve exponents (2)^2 = 4, so the equation is 3(4) - 2(2) + 1

3. Multiplication: 3 × 4 = 12, and -2 × 2 = -4, so the equation is 12 - 4 + 1

4. Addition: -4 + 1 = -3, so it is now 12-3

5. Subtraction: 12-3 = 9, so the answer is 9!

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

Three squares are shown. Each square is divided into 5 fifths.
A. 3 x 1/5= 3/5
B. 15 x 1/5 = 3
C. 15 x 3/5 = 9
D. 15 x 5/3 =25

Answers

Answer:

the answer is 2

Step-by-step explanation:

The equation which represent the three squares which is divided into the 5 fifths is,

[tex]15 \times \dfrac{1}{5} = 3[/tex]

What is a multiple of fraction?

A fraction number is the number which is a part of a whole number. It is written with a numerator and denominator. Fraction number are written as,

[tex]\dfrac{a}{b}[/tex]

Here (a) is the numerator and (b) is the denominator.

A multiple of a fraction is the number which is n times of the original function.

The model represents,

[tex]3 \div 1/5[/tex]

Here, the total number of square are given is 3. These three square are then divided into the one fifth.

Thus, we get total 3 times of 5 one fifth which is equal to the entire 3 squares

.

Thus, the equation can be written for this condition as,

[tex]15 \times \dfrac{1}{5} = 3[/tex]

Hence, the equation which represent the three squares which is divided into the 5 fifths is,

[tex]15 \times \dfrac{1}{5} = 3[/tex]

Option B is the correct option.

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

in the picture there is a Hyp and an Opp

so, use the function that has those  sin has those , huh

then,  

sin(Ф) = 12/13

Ф = arcSin(12/13)

Ф = 67.38 °

now we know that angle.. now we can get cos

cos(67.38 °) = adj / 13

13 * cos(67.38 °)  = adj

oh it's exactly

5 = adj

I feel like that's right since it worked out to be exactly 5  :)

Cos(Ф) = 5 / 13
