Solve for x!! need asap

x = 19

assume that the line under the triangle is a straight line, and the angle of any straight line = 180°,

collect like-terms

subtract

divide

to make sure of the answer, plug in the equation:

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)
