Question

I need help with 2 questions please thank you.

Answer 1

Hello!

Question 1

In a 30-60-90 triangle the hypotenuse is 2x the height is $x \sqrt{3}$ and the base is x

Find x

11 = 2x

Divide both sides by 2

5.5 = x

Put in x into the other equations

$5.5 \sqrt{3} = 9.5$

x = 5.5

2x = 11

11 + 5.5 + 9.5 = 26

We put the equations into a calculator and see which one is close to 26

The answer is B) 33/2 + 11/2 * the square root of 3

Question 2

For this one we can put the choices into a calculator and see what comes up close to 15

tan(86.19°) = 15.01

the answer is D) 86.19°

Hope this helps!
