Question

2. Find angle x in the following figures.



​

Answer 1

Answer:

x+35+115=180

x+150=180

x=30

therefore x = 30 degree

x+x+100=180

2x+100=180

2x=180-100

2x=80

x=80/2

x=40

therefore x= 40

115°-35°=80°

so,x is 80°

b)x+x=100°(sum of 2 internal angle is external angle)

2x=100°

100/2=x

50=x
