Answer 1

the value of x is 30, so the angles in the upper are 60, 30 and 90 in that order, also a is 60 and b is 40, then the lower angles are 40, 80 and 60

Answer 2

a = 60°, b = 40°, x = 30°

Explanation:

The top half:

2x + x + 3x = 180° (angles on a straight line sum up to 180°)

6x = 180° (divide both sides by 6)

x = 30°

Bottom half:

2x is vertically opposite to 'a' which means they are equal: 2x = a = 60°

180 - 60 (a) = 120° (angles on a straight line sum up to 180°)

b + 2b = 120° (simplify)

3b = 120° (divide both sides by 3)

b = 40°

Hope this helps!
