4 A series of isosceles triangles are drawn between two red line segments. A = 20°. Work out x , explaining each stage of your working in the comment box.

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=
