Answer: 90 degrees
============================
Explanation:
Let x and y be the two angles. Because they are supplementary angles, this means x+y = 180. Also since we're told that the angle is its own supplement, we can say that y = x.
Consequently, we can replace y with x and solve for x like so:
x+y = 180
x+x = 180 .... y is replaced with x since y = x
2x = 180
2x/2 = 180/2
x = 90
This means y = 90 as well. As a check, note how
x+y = 90+90 = 180
which verifies our answer.
Answer: x - 2.6 = 72.8
x is the number which Dan was thinking (x > 2.6)
we have:
x - 2.6 = 72.8

Step-by-step explanation:
it'll be these answers because you have to have a fraction in shapes that need to be finding the area of the shape
Answer:
4
Step-by-step explanation:
(f•g)(x) = -3(2x-6) -4
= -6x + 14
f•g(-7) = -6(-7) + 14 = 56
