The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is five times the measure of the first angle. The third angle is 16 more than the second. Let x, y, and z represent the measures of the first, second, and third angles, respectively. Find the measures of the three angles.

Step-by-step explanation:

z=y+16

y=y

:.z+y=5x where z=y+16

2y+16=5x

x=(2y+16)/5

.:z+y+x=180

y+16+y+(2y+16)/5=180

12y+80+16=900

y=67

z=16+67=83

x=30

three-fourths of an hour

36÷48=0.75

0.75=

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
