two angles are supplementary. what are the measures of two angles if the measure of the first angle is 40 more than half the second angle

and

Step-by-step explanation:

Two angles that are supplementary mean that they both add up to 180°.

If one angle is 40 more than half the second angle then,

a = + 40

Both angles together would be:

180 =

Step 1 - Subtract 40 from both sides of the equation:

Step 2 - Multiply both sides by 2:

Step 3 - Divide both sides by 3:

Step 4 - Plug this into the original equation to calculate the angle:

Therefore the two angles are:

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
