Question

Find the missing side.

Need help please. Need explanation, please.

Answer 1

x ≈ 12.22

Explanation:

SOH CAH TOA(Tangent = opposite side/adjacent side)

tan (48°) = x/11

=> x = tan (48°) × 11

=> x ≈ 12.22

Answer 2

This is basic trigonometry. First use SOH CAH TOA. Now look, you are finding opposite and adjacent so you use tangent. Now heres the equation - x/11 = tan48 now isolate the x. 11(tan48) = x.
Now plug into calculator and you get 12.2167
