Answer:
its b ez
Step-by-step explanation:
Multiple the top equation by 2 and rearrange so that -7 is equal to the others.
-10x+2y=-14
-3x-2y=-12
——————-
-13x=-26
Divide both by -13
x=2
<span>We should know that the sum of the interior
angles or an irregular polygon must be equal to 360°.
For examples, the case of
a square: 90° +90°+90°+90°=360°.
So in our case, the sum of the angles is
Sum=360°= (x+17)°+(2x+9)°+ (6x-5)° + meas OPQ,
it implies measOPQ=360°-(x+17)° - (2x+9)° - (6x-5)°
=360°-9x -31°=(329-9x)°</span>
