Answer 2

Answer:

1) 70 2)90

Step-by-step explanation:

1) in the first figure x and opposite to x are equal since it is a isosceles triangle

so 40+2x=180

2x=180-40=140

x=140/2=70

2) the angle opposite to 45 is equal to 45 only

since second triangle is also a isosceles

so 45+45+x=180

90+x=180

x=180-90=90

x=90
