Answer:

80°

Step-by-step explanation:

A rectangle has same opposite sides and 4 right angles as property of a rectangle.

The photo frame has different diagonal lengths

It makes opposite sides different, therefore it is not a rectangle

<u>Given angles (x - 20) and (x + 40) are consecutive interior angles which add up to 180°</u>

x - 20° + x + 40° = 180°
2x + 20° = 180°
2x = 160°
x = 80°

Slope of (-20,9) (14,9)

skelet666 [1.2K]

Y2-y1/x2-x1 is slope so

9-9/14-(-20) so you get 0/34 which means there is no slope since they have the same y (the equation would be y=0x+9 therefore y=9)
Which makes sense since the equation is a straight line
