Answer:
The measure of ∠A = 58.0°
Step-by-step explanation:
we will use the trigonometry function "tan" to solve the question
∵ BC is the opposite side of ∠A
∵ AC is the adjacent side of ∠A
∵ tan A =
∴ tan A =
∵ BC = 8 units
∵ AC = 5 units
∴ tan A =
→ Use the inverse function of tan to find the measure of angle A
∵ m∠A =
∴ m∠A = 57.99461679°
→ Round it to the nearest tenth
∴ m∠A = 58.0°
∴ The measure of ∠A = 58.0°
