Answer:
I put it in step by step because it is easier. (ans)
Step-by-step explanation:
Angle 1: It is a right angle so it is (90 degrees).
Angle 2: A triangle has 180 degrees. 90 plus 22 is 112 and 180 minus 112 is (68 degrees).
Angle 3: Since angles 2 and 3 are supplementary (2 angles summed to 180 degrees), 180 minus 68 is (112 degrees).
Angle 4: This is the same angle as 3 so it is also (112 degrees).
Angle 5: This is supplementary to 3 and 4 so 180 minus 112 is (68 degrees).
Angle 6: There are markings meaning the side lengths are the same. The angle opposite of its lengths are corrosponding. So meaning unnamed angle and 6 are the same. So 180-68 is 112 and 112/2 is (56 degrees).
Angle 7: We already know the unnamed angle is 56 degrees as it is the same as angle 6. Unnamed angle and 7 are supplementary. 180 minus 56 is (124 degrees).
Angle 8: It is the same as angle 7 (124 degrees).
