Answer 2

Okay first if you want to find the angle of 4, you have to complete the first triangle's angles.
So since the 2 angles that are in the triangle are 25° & 52°
Then you add them together and get 77°
Next you subtract 77° from 180°, so you should get 103° for angle 3
Finally you subtract 103° from 180° to complete line segment ←PAL
Final Answer: 77°
