Answer:
120°
Step-by-step explanation:
The angle just below 'x' is 40° (alternate angles/parallel lines)
40 + x + 20 = 180 ( straight line)
x = 120°

Where pi is defined as the ratio of a circle’s circumference
divided by the diameter of the its circle. Pi has a value which is 3.1416. This
pi is a constant value expressed by the quotient of its circumference over the diameter.
What type of number best describes the diameter is the pi. Hence, if we
describe the diameter, diameter is the quotient of pi over the circumference of
a circle by itself. It can’t change in value since for every solution and
quotient of a circle each calculation gets 3.14 more or less. </span>
Answer: 21 people voted
Step-by-step explanation:
an easy way to do this is simply multiply 84 * 0.25.
This gives you 
of the original amount

Answer:
15
Step-by-step explanation:
14-5=9 (a)
21-9=12 (b)
9x9=81, 12x12=144
144+81=225
What I do in my school is Part over a Whole equals % over 100.
So the whole is 80, the percent is 80% over 100. We need to find the part so we cross multiply. 80×80% is 1600. Divide that by 100 and u get 16 points.
HOPE THAT HELPS!
