Assuming PQRS is a parallelogram, we have PQ = RS, and angles S and R are supplementary so their measures sum to 180°.
So
5<em>x</em> = <em>x</em> + 12
4<em>x</em> = 12
<em>x</em> = 3
→ PQ = 5<em>x</em> = 15
and
12<em>z </em>° + 6<em>z</em> ° = 180°
18<em>z</em> ° = 180°
<em>z</em> = 180/18 = 10
→ m∠<em>S</em> = 12•10° = 120°
Step-by-step explanation:
since all 4 sides are equal in length, the figure is a square.
let the length of the square be lm.
529 = l x l
l = 23m
perimeter = 23 x 4 = 92m

Answer:
y is 8
Step-by-step explanation:
First u do 13y-9y=4y
so you then have 4y-5=27
then you plus 5 to 27
u then have 4y=32
then divide 32 by 4
so you will get y=8
