Two angles are complementary when their sum is 90 degrees and supplementary when their sum is 180 degrees
Thus for angle 44.4 degrees, the complementary is 90 - 44.4 = 45.6 and the supplementary is 180 - 44.4 = 135.6
Therefore, t<span>he complementary angle is 45.6 and the supplementary angle is 135.6</span>
C because this is the only triangle that has a non included angle leaving 145 degrees to create another triangle

Answer:
x = 17 y= -38
Step-by-step explanation:
x + y = -21
y = x - 55
It doesn't matter whether x or y is 55 less than the other right now.
<u>substitute for y:</u>
x + x - 55 = -21
<u>solve for x:</u>
2x = 34
x = 17
<u>solve for y:</u>
17 + y = -21
y = -38
Answer:
0
Step-by-step explanation:
The slope of a line is also known as the change in the line. it is often referred to as () and can be found using the formula, (). Substitute in the given points and solve for the slope,
Simplify,
The slope of the line is (0).
