Question

In angle ABC,A+B=65 and B+C=140 find the angle of B angle C
​

Answer 1

Answer:

here is the answer

Step-by-step explanation:

Given:- A+B = 65°

So, A = 65-B........(i)

B+C = 140°.........(ii)

A+B+C = 180° { Angle sum property}

65-B +B +C = 180 (from i)

65 + C = 180

C = 180 - 65

C = 115°

Put this value on (ii)

B+C = 140

B + 115 = 140

B = 140 - 115

B = 25°
