If an angle of 145 is divided into 5 angles with ratios 1: 3: 5: 8: 12, what is the measure
of the 4th largest angle?

15 °

Step-by-step explanation:

The five angles are splitted in the ratio 1:3:5:8:12

The 1st biggest angle is at ratio 12

The 2nd biggest angle is at ratio 8

The 3rd biggest angle is at ratio 5

The 4th biggest angle is at ratio 3.

Time solve for the 4th biggest angle, we will find the sum of the ratios:

Therefore, 1 + 3 + 5 + 8 + 12 = 29

Ratio of 4th biggest angle:

= (3)/(29). * 145

= (3 * 45) / 29

= 3 * 5

= 15 °

answer:

your answer is: c. 196 7/8 in^3.

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
