Find two supplementary angels such that the measure of the first angle is 38° less than three times the measure of the second
stiks02 [169]


angle 1+ angle 2=180    supplementary angles add up to 180

angle 2=x     assign angle a variable

angle 1= 3x-38      find equation for first angle

3x+x-38=180      set both angles added together equal to 180

4x-38=180        combine like terms

4x=218        add 38 to both sides

x=54.5        divide by 4

angle 2= 54.5

angle 2= (3x54.5)-38   plug back in and solve

angle 1= 125.5

the price of a jacket was increased from $140 to $168 what was the percent increase in the price of the jacket
kenny6666 [7]

Subtract to find the amount of the increase:

168 - 140 = 28

The increase in price was $28.

Now divide the amount of increase by the original price.

This will give you a decimal, then multiply the decimal by 100 to get the percent:

28 / 140 = 0.2

0.2 x 100 = 20% increase.
