Question

find angel a,b,c.if exterior angel is 110and 135 ​

Answer 1

As we know that the sum of angles of a triangle is 180

Here,

angle A + angle B =110

angle A + angle C= 135

now,

180 = (angle A + angle B) - angle A + (angle A + angle C)

180= 110 + 135 - angle A

180 - 110 - 135 = angle A

180-245 = - angle A

- 65 = - angle A

65= angle A
