Two angles are supplementary. The measure of one angle is 16 more than two times the measure of the other
angle. How many degrees are in each angle?

82 and 98.

Step-by-step explanation:

set up 2 equations

x+y=180

2x+16=180

you start by solving the second equation to find one of the angles.

180-16= 164

2x=164

164÷2= 82

x=82

since you've solved that equation, add in the missing variable to solve for the next one

82+y=180

180-82= 98

after 6 years he will gain $660 in interest because 0.055 • 2000 • 6 = 660
