Answer:
∠ O = 72°
Step-by-step explanation:
the inscribed angle R is half the measure of its intercepted arc NQ , then
arc NQ = 2 × 36° = 72°
the central angle O is equal to the measure of the arc that subtends it , so
∠ O = arc NQ = 72°
Answer:
x=2y-8
We use the substitution of x in the second equation
2*(2y-8)+3y= -2
4y-16+3y=-2
7y-16= -2
7y= -2 +16
7y=14
y=14Ș7
y=2
so x= 2*2 -8
x=4-8
x=-4
the solution is (x,y)=(-4, 2)
