Answer 1

Answer:

130°

Step-by-step explanation:

According to Angle Sum Property of triangle, the sum of all three interior angles of a triangle is 180°.

=> A + B + C = 180°

=> 100° + B + 30° = 180°

=> B = 180° - 130°

=> B = 50°

Angle x and Angle B form a linear pair.

Therefore, x = 180° - 50° = 130°.

Answer 2

Answer:

50

Step-by-step explanation:

<A=100

<C=30

<B=?

<B=100+30+X=180

<B=130+X=180

<B=180-130

<B=50
