e°=100°

Step-by-step explanation:

Sum of angles in a triangle= 180°

70°+30°+x°=180°

100°+x=180

Collect like terms

x°=180-100

x°=80°

e° is an exterior angle

exterior angle =180- interior angle

180°- x°

180°- 80°

=100°

e°=100°

(d)100

explanation:

Because the outer angle equals to the measure of the inner angles
