Answer:
Angle A is about 61.9 degrees
Step-by-step explanation:
To find the measure of an angle, we can use inverse trigonometry. To find A, we can use the formula A=sin^-1(opposite/hypotenuse).
The side opposite of angle A is 15, and the hypotenuse of the triangle is 17. We can plug in the numbers into the calculator to get:
A= sin^-1 (15/17)
A= 61.9275
We round to 61.9.
