Question

In the given figure,angle ABC=80°,angle=ACE=70°.If AB is parallel to CE, then find the measure of angle ACB.​

Answer 1

Answer:

ace=bac

bac =70

70+80+acb=180

Acb=180-150

ACB=30

Step-by-step explanation:

Answer 2

Answer:

angle ACE= angle CAB. (alternate angle)

so in triangle BAC

angle ABC + angle ACB + angle CAB=180°

80°+ angle ACB + 70°=180°

angle ACB+150°=180°

angle ACB=180°-150°

angle ACB=30°
