Question

If we assume the measure of B gº А Measure of Ze

Answer 1

Answer:

c = 55° and d = 125°

Explanation:

Given that,

$\angle a=85^{\circ}\\\\\angle b = 40^{\circ}$

We need to find the measure of angle c and angle d.

We know that the sum of angles of a triangle is 180 degrees. So,

a+b+c = 180

85+40+c = 180

125+c=180

c = 180-125

= 55°

Using exterior angle theorem,

d = a+b

d = 85+40

d = 125°

Hence, c = 55° and d = 125°
