Pls help math and yet i still do not understand

x = 65º

Step-by-step explanation:

Isoceles Triangle Theorem: If the two sides of an isoceles triangle are congruent, then angles opposite those sides are congruent.

Therefore x = 65º

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=

−9

2

x+10
