Answer: x = 45</h3>
Work Shown:
x+x+90 = 180 .... all three angles of a triangle add to 180
2x+90 = 180
2x = 180-90
2x = 90
x = 90/2
x = 45
This is a 45-45-90 right triangle. We also consider it an isosceles right triangle because the base angles (45) are equal.
The answer is no, the side lengths are not persevered. <span />

If BA is d units the CB must be 2d units. B is on the x-axis, 2d units
right of C so its coordinates are (2d, 0). A is d units above B at (2d,
d). </span>
Answer:
Step-by-step explanation:
divided by is the same thing as multiplying by .
The equation we get is:
With this equation, we can factor each equation:
We can cancel out like terms since they would be dividing each other:
