Question

In ∆ABC, ∡A=100°, ∡A=2∡B, find ∡C in radians.

Answer 1

Answer:

0.524 rad

Step-by-step explanation:

A=100°

A=2B or B=A/2

B=100/2

B=50°

Sum of all angles of a triangle =180

ie; A + B + C = 180°

100°+50°+C =180°

150 +. C = 180°

C=180-150

C=30°

30°X pi/180=0.524radian

(pi=3.14 if you don't know it's value)
