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°

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

the answer is 31.27mph
