Question

Can someone help me with geometry please

Answer 1

Angle 1 = 51
Angle 2 = 18
Angle 3 = 123
angle 4 = 39

Explanation:

∠1 + ∠2 + ∠3 = 180

Angle 1 + 72 + 57 = 180
Angle 1 = 180

90-72 = Angle 2
Angle 2 = 18

180-57 = Angle 3
Angle 3 = 123

∠1 + ∠2 + ∠3 = 180

Angle 2 + Angle 3 + Angle 4 = 180

18 + 123 + Angle 4 = 180
Angle 4 = 39
