∠3,∠ 8, and ∠4

Answer 1

Answer:

angle 6&8 and 5&2 are supplementary angles.

angle 3 is 90⁰,

Angle 8 is 180-137= 43⁰,

Angle 4 is 180-34= 146⁰.

Answer 2

$<3= 90° , \: <8 = 43° , \: <4 =146°$

Step-by-step explanation:

$\: <3 = <1 = 90° \\ \\ <8 = 180°-<6 \\ = 180°-137° = 43° \\ \\ <4 = 180°-<2 \\ = 180°-34° = 146°$
