Answer:
• Assume Q is a mid point of line MY
• Then, MQ = YQ
3. x+100 = 90 alternate interior angles are equal
subtract 100 from each side
x+100 - 100 = 90-100
x = -10
4. 17x+1 = 120 alternate exterior angles are equal
subtract 1 from each side
17x+ 1 -1 = 120 -1
17x = 119
divide each side by 17
17x/17 = 119
x =7
<span>Because you have changed the sign of the divisor as part of setting up the synthetic division.
The whole point of changing the divisor's sign is allow addition (which is easier) instead of subtraction.</span>
