Find the slopes of the sides of the triangles:
Slope of AB = 9
Slope of BC = 1
Slope of CA = -1
The triangle is a right triangle as BC and CA are perpendicular* to each other, which means that angle ACB = 90.
* If a slope is the negative reciprocal of another slope, they are perpendicular

hope this helps.
if you ever need helping with graph, Desmos graphing calculator is really helpful. (its a website, just search it up)
Length = area/width
.. = (41 2/3 in²)/(4 1/4 in)
.. = (125/3 in²)/(17/4 in)
.. = (125/3)(4/17) in
.. = 500/51 in
.. = 9 41/51 in
