Write an expression for the perimeter of the triangle shown below
0.3x+24
5x
0.2x-15

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

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
