Question

One angle of a triangle is 65º. Find the remaining two angles if their difference is 20.
​

Answer 1

Answer:

Let the three angle be A, B, C

Given A = 65 degree, B - C =20 degree

C = B - 20

Sum of the three angles of a triangle is 180 degree

A + B + C = 180

65 + B + ( B - 20)=180

2B = 180 - 65 + 20 = 135

B = 135 ÷ 2

= 67.5

C = B - 20

C = 67.5 - 2

= 47.5
