Answer:
False! However all equilateral triangles are acute
The slope-intercept form:

m - slope
b - y-intercept
We have the points (1, -5) and (9, 11). Substitute:

Therefore we have

Put the coordinates of the point (1, -5) to the equation:

<h3>Answer: y = 2x - 7</h3>
The triangles ABC and ADC are similar.
Therefore
I think the answer is 58, but im not 100% sure so im sorry if it is wrong
Thats easy the answer is b
