A same side interior angle of two parallel lines is 20° less than the other same side interior angle. Find the measures of these two angles.

The measures of the two angles are 80 and 100

Step-by-step explanation:

Let and represent the two angles such that

Required

Find and

The two angles of a same-side interior angle of parallel lines add up to 180;

This implies that

Substitute for

becomes

Collect like terms

Divide both sides by 2

Recall that

Hence, the measures of the two angles are 80 and 100

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

won't that be plagrisim thought?
