Answer:
if two parallel lines are cut by a transversal, then alternate interior angles are <em>congruent</em><em> </em>
This is a right angle.
So... 7z+3z=90
10z=90
Z=9
The larger angle is thus 7(9)=63 degrees
Answer:
152
Step-by-step explanation:
1. 9 x 8 = 72
2. 1 x 8 = 8
3. 8 + 7 = 15
or
8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8
or
19 + 19 + 19 + 19 + 19 + 19 + 19 + 19
