Answer:

Sin A= 5/13

Cos A= 12/13

Tan A= 5/12

Step-by-step explanation:

The memory trick most people use is for sin, cos, and tan, they call it SOH, CAH, and TOA where the A means Adjacent, the H means Hypotenuse and the O means Opposite. so sin would be Opposite/Hypotenuse, cos is Adjacent/Hypotenuse, and tan is Opposite/Adjacent.

Because the Hypotenuse is not given, we must use the formula A^2+B^2=C^2 where A is the height, B is the width, and C is the slope side. You will get C=13 if you do it correctly. Now you can solve for Sin, Cos, and Tan

Sin A= 5/13 (Opposite/Hypotenuse)

Cos A= 12/13 (Adjacent/Hypotenuse)

Tan A= 5/12 (Opposite/Adjacent)

Hope this helps.

Have a great day!

Sin(A) = opposite/hypotenuse = 12/13

Cos(A) = adjacent/hypotenuse = 5/13

Tan(A) = opposite/adjacent = 12/5

The surface area for a rectangular prism with a square base is SA=2s2+4sh. What is the surface area if s=3 and h=5?

Zigmanuir [339]

Answer:

The surface area is 78 unit square.

Step-by-step explanation:

Given : The surface area for a rectangular prism with a square base is $SA=2s^2+4sh$ .

To find : What is the surface area if s=3 and h=5?

Solution :

The surface area for a rectangular prism with a square base is $SA=2s^2+4sh$

Substitute, s=3 and h=5

$SA=2(3)^2+4(3)(5)$

$SA=2\times 9+4\times 15$

$SA=18+60$

$SA=78$

Therefore, The surface area is 78 unit square.

1.What is the y-intercept of the plane whose equation is 4x + 5y – z = 20?

Katena32 [7]

In case of plane, for y intercept, x and z are o .

So we will get

4(0)+5y-0=20

5y=20

Dividing both sides by 5

y = 4

So the y intercept is (0,4,0).

In second question, x intercept is 1, y intercept is -1 and z intercept is 2 .

So the correct option is the third equation , that is x-y+2z=4 .

Kevin is three years older than Daniel. Two years ago, Kevin was 4 times as old as Daniel.

GarryVolchara [31]

Answer:

I believe that Kevin is 6 years old now.

Step-by-step explanation:

I used the guess and check method to figure this out.

First, I began by making Daniel 1 years old, two years ago. Kevin was 4 times as old as Daniel two years ago, so he would be 4 at the time. Now, Daniel would be 3 and Kevin would be 6 years old. The statement that Kevin is three years older than Daniel would confirm this, because 6-3=3. Hope this helps, this is my first time answering:)
