Question

PLS HELP WILL MARK BRAINLIEST!! TY

Answer 1

Step-by-step explanation:

$\angle{1} = 77°$ because they are vertical angles.

The 77°-angle is supplementary with $\angle{2}$ therefore

$77° + \angle{2} = 180° \Rightarrow \angle{2} =180° -77° = 103°$

$\angle{3}$ and $\angle{2}$ are vertical angles so

$\angle{3} = \angle{2} = 103°$

Answer 2

Answer:

103 = angle 3

103 = angle 2

angle 1 = 77

Step-by-step explanation:

angle 1 = 77

angle 2 = angle 3

360 - 77x2 = 206

206/2 = 103
