Question

In ABC, m∠A + m∠B = 105 and m∠B + m∠C = 115. Find m∠A and m∠C​

Answer 1

Answer:

angle a = 65, angle c = 75

Step-by-step explanation:

Given a + b = 105

Given b + c = 115

a + b + c = 180

b + c = 115

180 - 115 = 65 measure of angle a

105 - 65 = 40 measure of angle b

115 - 40 = 75 measure of angle c
