Two angles are supplementary if the sum of their measures is 180.
anastassius [24]
True.

two angles would be complementary if the sum of their angle measures is 90 degrees.

60 degrees and 30 degrees make a complementary angle while 90 and 90 degrees make a supplementary angle.

Solve the following system : -x + 5y = 8 and 3x + 7y = -2
poizon [28]

-x + 5y = 8

multiply this equation by 3

-3x + 15y = 24

now add it to the other equation  ( elimination)

-3x + 15y = 24

3x + 7y = -2

-----------------------

0x  + 22 y = 22

divide each side by 22

y =1


substitute into -x + 5y =8  to find x

-x + 5(1) = 8

-x + 5 = 8

-x =3

divide by -1

x =-3

Answer (-3,1)

Choice A
