If cf = 5, cd = 12, and ef = 5, what is the perimeter of triangle cde?

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
