Two supplementary angles have measures of x + 7 and 2x-4. what is the measure of each angle?

the angles are 66 and 114

Step-by-step explanation:

supplementary angles add to 180

x+7 + (2x-4) = 180

combine like terms

3x+3 = 180

subtract 3 from each side

3x+3-3 = 180-3

3x = 177

divide by 3

3x/3 = 177/3

x = 59

x+7 = 59+7 = 66

2x-4 = 2 (59) - 4 = 118 - 4 = 114
