John is offered a new job with a starting apt of $10.00 per hour and he will receive a $0.50 raise after first year. For each year that he stayed with the company after that, his raise will be $0.50 more than it was the year before. How much will John make per hour in his 7th year working for the company?

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
