Answer:
6.) angle 1 = 61 degrees. angle 2 = 61 degrees. . 7.) angle 1 = 44 degrees
angle 2 = 44 degrees
Step-by-step explanation:
main reason is that because of Alternate Interior angles theorem angle 1 = angle 2
for both questions 6 and 7.
Also the angles that form a straight line sum to 180 degrees
so 61 + 58 + 61 = 180
and for 7
90 = 46 + 44
