Suppose M is the line with equation x=-5, line N is the line with equation y=1, line G is the line with equation y=x, and line H is the line with equation y=-2. Given A(9,-3), B(6,4), and C(-1,-5), what are the coordinates of the vertices of triangle A'B'C' for a reflection across line G? (put your answers in coordinate form)

Wait, so you want us to make a coordinate grid?

Step-by-step explanation:

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°
