are they angles?
OpenStudy (cookiemonster2412):
yes
OpenStudy (hoblos):
in a parallelogram opposite angles are equal ---> 8a-10=5b+6 the sum of two adjacent angles is 180 ---> 4a-8 +8a-10 = 180 so now you have a system of two equations, can you solve it ?
OpenStudy (cookiemonster2412):
yes thank you
