Answer :
Answer:
Option A is the correct answer
Step-by-step explanation:
Firstly, please check attachment for diagram of triangle.
To calculate the value of the angle A, we employ the use of trigonometric identities.
What we have in the question are the two other sides, other than the hypotenuse. These are the opposite and the adjacent.
The opposite is the side facing the angle while the adjacent is the other third side.
The trigonometric identity we have to use here is the tan, since
Tangent of an angle = length of opposite/length of adjacent
The length of the opposite here is 14 while the length of the adjacent is 18
Thus,
Tan A = 14/18
Tan A = 0.7778
A = arc Tan (0.7778)
A = 37.87 which is 37.9 degrees
