I'm really confused... angle_1and angle_2 are supplementary angles. measure of angle_1 is 4y + 7 and measure angle_2 is 9y + 4. Find measure of angle_2.

OpenStudy (anonymous):

okay so you have 4y + 7 + 9y + 4 = 180 since they are supplementary now solve for y

OpenStudy (anonymous):

13y + 11 = 180

OpenStudy (anonymous):

okay so I just have to subtract 11 from both sides then and divide by 13 right?

OpenStudy (anonymous):

right
