Answer:
The answet is C.
Step-by-step explanation:
First, you have to find the angle of ACB using Sine Rule, sinθ = opposite/hypotenuse :
Given that line AB is parallel to line CD so ∠C = 90°. Next, you have to find the angle of ACD :
Lastly, you can find the length of CD using Cosine rule, cosθ = adjacent/hypotenuse :

Answer: 3780
Answer:
The ∠B prime A prime C prime in the resulting figure = 90°
explanation:
The coordinates of the right triangle = A( -1, 4), B(-1, 8) and C(3, 4)
The rotation 90° counterclockwise of a point on a preimage (x, y) gives the coordinates of the location of the point of the image after rotation as (-y, x)
Therefore we have;
Applying 90° counterclockwise rotation we have;
The point A(-1, 4) is relocated to the point (-4, -1)
The point B(-1, 8) is relocated to the point (-8, -1)
The point C(3, 4) is relocated to the point (-4, 3)
The answer for the problem is -13x+8
