Answer:
c = 55° and d = 125°
Explanation:
Given that,
[tex]\angle a=85^{\circ}\\\\\angle b = 40^{\circ}[/tex]
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°
