i havent seen a problen like this

4. hartnn

Adjacent angles of a parallelogram are supplementary, so y+3y =180 can you find 'y' from here ?

5. Reaper534

4y=180 y=45

6. Reaper534

howwould i finx do i 3x=180 x=60?

7. hartnn

sorry for late reply! again Adjacent angles of a parallelogram are supplementary, y+3x =180 and you know y :)

8. hartnn

or you could use the fact that opposite angles are equal, 3x=3y x=y :)

9. Reaper534

45+3x=180 3x=135 x=45 thx alot man
