Question

Round your answer to the nearest hundredth LA

Answer 1

Answer:

Step-by-step explanation:

Since this is a right triangle, we will use a right triangle trig identity to solve our problem. The side opposite the reference angle A is given as 5, and the side adjacent to the reference angle is given as 7. The trig ratio that uses the sides opposite and adjacent is the tangent ratio:

$tanA=\frac{5}{7}$

Hit the 2nd button on your calculator then the tan button which displays:

$tan^{-1}($

Enter 5/7 after that open parenthesis and hit = to get that

A = 35.54°
