Question

Could someone help out?

Answer 1

27.18

Explanation:

Firstly, you must label the triangle.

r- opposite

13.85- adjacent

We know that tan θ = opposite/ adjacent so we substitute our numbers into the equation.

tan (63) = r/13.85

Then, times 13.85 on both sides so we only have our unknown on one side.

(x13.85) tan(63)= r/13.85 (x13.85)

r= tan (63) x 13.85

r=27.18
