7 × 6 = 42 Answer
hope it helps
You solve for one variable like
y-5x=2
"y=5x+2"
9x+3y=58
and you plug it in into the other equation
9x+3(5x+2)=58
You solve for x and then plug in your answer for x into the other equation
*let's imagine x=8*
then:
y-5(8)=2
and solve for y

Your answer is 27 I pretty sure sorry if it’s wrong.
<h3>Answer: 72 degrees</h3>
================================
Explanation:
Use the inscribed angle theorem to go from inscribed angle D = 66 to 2*66 = 132. The central angle is double that of its corresponding inscribed angle.
This means arc ABC has measure 132 degrees.
The minor arc BC is 97 degrees, so
(minor arc AB) + (minor arc BC) = arc ABC
(minor arc AB) + (97) = 132
minor arc AB = 132-97
minor arc AB = 35
and
(minor arc DA) + (minor arc AB) = arc DAB
(109) + (35) = arc DAB
144 = arc DAB
arc DAB = 144
Now use the inscribed angle theorem again. Cut the arc measure DAB in half to get its corresponding inscribed angle measure (angle C)
144/2 = 72
<h3>angle C is 72 degrees</h3>
