Question

Can someone help with this thank you so much .

Answer 1

Explanation:

we know both angles together (which is angle ABD) are 118°.

so,

angle 1 + angle 2 = 118°

angle 1 = angle 2 + 12

now we use the second equation in the first one :

(angle 2 + 12) + angle 2 = 118

2×angle 2 + 12 = 118

2×angle 2 = 106

angle 2 = 53°

and angle 1 = angle 2 + 12 = 65°
