Answer:
77*
First we are going to take our given number, 25* and 78* and add them together.
25* + 78* = 103*
And subtract our answer, 103*, from 180*.
180* - 103* = 77*
77* is our missing angle. To prove it, we add angle measures a, b, and c, to make the number 180*
25* + 78* + 77* = 180*
Another way to write it is . . .
180* - (A + B) = C

Answer:
16
notice how a right triangle was formed, and the Pythagorean theorem could be used to solve this :
a^2 + b^2 = c^2
a^2 + 15^2 = 17^2
a^2 + 225 = 289
a^2 = 64
a= 8
multiply it by 2 to get the side of the base
8 * 2 = 16
Answer:
slope = 
Step-by-step explanation:
Use the slope formula given in the question to solve for the slope. The 
is the variable representing the slope. The 
and 
values are x and y values of one point. The 
and 
are x and y values of another point.
So, use the x and y values of the points given and substitute them in the correct order into the formula:
Thus, the slope is .
