m<1 = 69°

Step-by-step explanation:

Angles 20x + 11 and 25x - 14 are vertical angles, so they are congruent.

25x - 14 = 20x + 11

5x = 25

x = 5

The actual measure of angle 20x + 11 is 20(5) + 11 = 111°.

Angle 20x + 11 and <1 are supplementary, so the sum of their measures is 180°.

m<1 + 111° = 180°

m<1 = 180° - 111°

m<1 = 69°

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
