Answer:

8.090169944 or rounded 8.1

Step-by-step explanation:

Use SOH CAH TOA

Look at x and where it is and what you have.

First thing is to get an angle to use, 36, then to set up your equation.

___(36)=___

Figure out what you have.

You have the hypotonouse, 10, and need the adjacent,x, so you use the equation that involves H for hypotonouse and A for adjacent.

You set up your equation using COS, as you are using CAH.

Cos(36)=x/10

X is over ten sure to CAH C-cos A-adjacent and H-hypotonouse

Switch it around to make it equal to x

10*Cos(36)=x

You input it into your calculator. [10] [COS] [36] [ENTER] and you get the answer.

Round however is needed.
