Idon't know how to solve the problem

Dur

ok, so those lines are paralell
and therefor those 2 angles add to 180
x+96+x+96=180
2x+192=180
minus 192 both sides
2x=-12
divide by 12
x=-6

sub back
x+96=
-6+96=
90
90 degrees

Your answer would be ahere is how: perimeter is how long all the sides are. in a rectangle, there are two sets of parallel sides. so, to find this, we would to the following.(15x2)+(4x2)30+838if you have questions ask! and mark me brainliest! i really wanna level up : 3

Ithink the answer is $2.10
