Question

The angles of a triangle are in A.P. and the greatest angle is 84°. Find all the three angles in radians.

Answer 1

Answer:

Step-by-step explanation:

let angles be:- a - d, a, a + d

now,

a - d + a + a + d = 180

3a = 180

a = 60

greatest angle = a + d = 84

d = 24.

so the angles are

a - d = 36 = 36 * $\frac{\pi }{180}$=$\frac{\pi }{5}$

a = 60= 60* \frac{\pi }{180} =$\frac{\pi }{3}$

a + d = 84 = 84* \frac{\pi }{180} =$\frac{7\pi }{15}$

hope it helps.. regards
