What is the value of x? enter your answer in the box. ft triangle v t k with segment t y such that y is on segment v k, between v and k. angle v t y is congruent to angle y t k. v t equals 77 feet, v y equals 22 feet, v k equals x, and t k equals 87.5 feet.

47 ft

Step-by-step explanation:

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
