An angle measures 30° more than the measure of its complementary angle. What is the measure of each angle?

60 degrees and 30 degrees

Step-by-step explanation:

If you really want, you can set up a system of equations using the given information. X can the larger angle and Y can be the smaller angle.

x + y = 90

x = y + 30

In reality, this is not necessary for such a simple problem. Some trial and error testing would help you figure this out much faster.

the anwser is d) 75°

step-by-step explanation:

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
