Answer:
Question 12: 60°
Question 13: 30°
Question 14: 60°
Question 15: 120°
Step-by-step explanation:
Question 12: The measure of a circle is 360°, so ∠CGD which is 
of a full rotation is 60°.
Question 13: ∠CGH is 
of ∠CGD, so its angle measure is 30°.
Question 14: Since the interior sum of all angles in a triangle is 180° and two angles have measures of 90° and 30°, that means ∠HCG has a measure of 60°.
Question 15: Since ∠EGC is 
of a full rotation, and is twice as great as ∠CGD, that means it has an angle measure of 120°.
Answer:
m∠2 = 98°, m∠3 = 82°
Step-by-step explanation:
I'm going to assume this is a straight angle
Supplementary angle are two angles that equal 180°
m∠2+m∠3=180°
<h3>-Substitute</h3>
m∠2+m∠2-16=196°
<h3>add both side by 16°</h3><h3 />
2m∠2=196°
<h3>Divide both sides by 2</h3><h3 />
m∠2=98°
Since we said m∠3 = m∠2 - 16°
m∠3 = 82°
I believe it would be 1:7, since both are divisible by 9. Hope this helped! :)
Answer:
16×16=256
20×20=400
multiply the number with its self and that's the square inches of each pizza.
