Answer:
7.D) 107°
8. A) 123°
Step-by-step explanation:
To find the correct measurement of the angel the sum of the interior angels needs to equal 360°. Angels where the lines intersect with the circle would be both 90°. ( If that makes sense.)
90°+90°=180
180°+73°= 253°
360°-253°= 107°
The same for the second one. (those two angles would also be 90° each.)
90°+90°=180°
180°+57°=237°
360°-237°=123°
Answer:
