Step-by-step explanation:
Supplementary angles add up to 180 degrees
Complementary angles add up to 90 degrees
It is just a rule that is important to geometry
I hope that helps :)
The formula for the distance between two points is
Note that, if two points have one coordinate in common, this formula simplifies to
(the first if they share the y coordinate, the second if they share the x coordinate).
So, these are the lengths of the sides:
(because they share the y coordinate)
(standard formula)
(because they share the y coordinate)
Answer:
x = 17
Step-by-step explanation:
29 + 29 + 11x - 65 = 180
58 + 11x - 65 = 180
58 + 11x + 65 = 245
58 + 11x = 245
-58 + 11x = -58
11x = 187
x = 17
