Which series of transformations would transform triangle A into similar triangle A' in Quadrant IV?

A. Rotate triangle A 90 clockwise about the origin then translate five units up

B. Dilate triangle A by a scale factor of 4. Translate triangle A to the left.

C. Reflect triangle A across the y-axis and then translate the triangle 3 units up and 2 units to the right.

step-by-step explanation:

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
