The measure of the angle A is 49.99 degree or 50 degree if the length of AB = 14 and AC = 9.
What is trigonometry?
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
The question is incomplete:
Question is: In the diagram of right triangle ABC shown below, AB = 14 and AC = 9 What is the measure of ∠A, to the nearest degree?
We have a given a right angle triangle in the picture
It is required to find the measure of angle A
Applying cos ratio to find the measure of the angle A:
cosA = 9/14
cosA = 0.642
A = 49.99 ≈ 50 degree
Thus, the measure of the angle A is 49.99 degree or 50 degree if the length of AB = 14 and AC = 9.
