Answer:
The tan(a) is the degree value of the angle shown. In this case, the unknown degree is A, and it wants you to use the Tangent method. Using the formula to get 27°
Explanation:
Tangent (A) = opposite (√17) over adjacent (8)
So it would be Tan(A)= √17/8
To easily solve this use a calculator
Find the tan button, (use the inverse tangent or tan-1)
then sub values
tan-1(√17/8)
27.26 or 27°
