Answer:
angle 2 = 37⁰
angle 3 = 153⁰
angle 4 = 37⁰
Step-by-step explanation:
I guess this refers to two intersecting lines which form 4 angles.
Angles 1 and 2 are supplementary angles whose sum is 180⁰.
Angle 1 + angle 2 = 180⁰
143⁰ + angle 2 = 180⁰
angle 2 = 180⁰ - 143⁰
angle 2 = 37⁰
Angles 1 and 3 are vertical angles so do with angles 2 and 4. Therefore it is easy to find their measures because vertical angles are congruent in measures.
