1 foot is 12 inches. So just divide 81 by 12.
81/12 = 6.75
So your answer is 6.75 feet.
If you got 55.6% on a test and that test is worth 80%
So first let us calculate the actual percentage that you scored.
The actual percentage is
So your actual score on the test is 69.5%
The grading system varies across countries and states
The traditional grading scale is given below
90% to 100% corresponds to A grade.
80% to 89% corresponds to B grade.
70% to 79% corresponds to C grade.
60% to 69% corresponds to D grade.
0% to 59% corresponds to F grade.
69.5% can be rounded off to 70%
Therefore, 69.5% corresponds to C grade.
(note: the above grade is not valid in case your school follows a different grading scale)
Answer:
b is the angle being measured while a is the angle at a point with b
Step-by-step explanation:
The only time we use 360 for calculating an angle is when the two angles are at a point as both of them assuming a and b sum up to 360°.
Therefore a + b = 360
and if b is being measured, b = 360 -a
