Solve the system of equations by elimination.
x +y=-13
8x - 4y = -8

The supplement of the larger angle is 108°.

Step-by-step explanation:

Step 1:

If two angles are complementary, the sum of the angles will be equal to 90°.

If two angles are supplementary, the sum of the angles will be equal to 180°.

If angle m and n are complementary, the sum of angles m and n will be 90°.

Also assume angle m is four times the angle n.

So

So

so m is 72° and n is 18°.

Step 2:

Angle m is the larger angle.

Assume angle m and angle o are supplementary.

Angle m + angle o = 180°.

Angle o

So the supplement of the larger angle is 108°.
