Answer:

A. \frac{3 - 7}{-4 -(-7)} = \frac{-5 - 3}{2 - (-4)}

Step-by-step explanation:

Slope of PR = \frac{y_2 - y_1}{x_2 - x_1}

Where,

P(-7, 7) = (x_1, y_1)

R(-4, 3) = (x_2, y_2)

Slope of PR = \frac{3 - 7}{-4 -(-7)}

Slope of RT = \frac{y_2 - y_1}{x_2 - x_1}

Where,

R(-4, 3) = (x_1, y_1)

T(2, -5) = (x_2, y_2)

Slope of RT = \frac{-5 - 3}{2 - (-4)}

Therefore, the proportion that can be used to show that the slope of PR = the slope of RT is:

\frac{3 - 7}{-4 -(-7)} = \frac{-5 - 3}{2 - (-4)}

AB is 15 because AB=AC and AC is 15

BD:

Using the Pythagorean Theorem

10²+15²=√325

√325=18

10 is from AB-CD

15 is the height which is AC
