emma reflected the triangle across the x axis and then rotated the figure 90 degrees counterclockwise about the origin. which
triangle a'b'c' did she end up with?

y=mx+b

step-by-step explanation:

m slope, b y-intercept

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

to be honest i don't know but i need points so
