The measures of complementary angles have a sum of 90 degrees.Angle A and angle B are complimentary, and their measures have a d
777dan777 [17]

Answer:

The measure of the angles are 55° and 35°

Step-by-step explanation:

Sum of two angles that are complement of each other are 90.

The angles are A and B, so we can write:

A + B = 90

Also,

The difference is 20. Let A be the greater of them, so we can write equation 2 as:

A - B = 20

Now, we add up both equations, eliminate B and solve for A first:

A + B = 90

A - B = 20

---------------

2A = 90 + 20

2A = 110

A = 110/2

A = 55

And now the measure of B:

A + B = 90

55 + B = 90

B = 90 - 55

B = 35

In six months the membership at a fitness center went from 3,500 to 4,200. what was the percent of increase in the membership?
slega [8]
It is definitely C: 20%

Subtract the original value from the new value, then divide the result by the original value then multiply the result by 100 and it will give you the answer

\frac{4200 - 3500}{3500}  \times 100
\frac{700}{3500}  \times 100
0.2 \times 100 = 20\%
