PQ is the tangent, therefore you can use a theorem: The arc measure is double the amount of the angle the tangent makes.
So: 62/2=31
Your answer is 26.9 so u could round it up to 27
(6/5.55) * 100 = 108.11 %
The percent error is 108.11 %
You could understand the ration as parts: the total number of parts was 3+7=10.
So girls were 3/10 parts and boys 7/10 parts. The difference was 7-3=4 parts. this difference is equal to 360, so each part is 90 (4*90 =360).
so girls are "3 parts" and each part is 90, then the number of girls is 3*90=270.
Answer:
Step-by-step explanation:
In mathematics, a curve (also called a curved line in older texts) is an object similar to a line but that need not be straight. Thus, a curve is a generalization of a line, in that its curvature need not be zero.
