Answer:
Angle 1: 52 degrees
Angle 2: 128 degrees
Step-by-step explanation:
Angle 1 = x
Angle 2 = 2x + 24
Supplementary angles are two angles that add up to 180 degrees.
x + 2x + 24 = 180
3x + 24 = 180
3x = 180 -24
3x = 156
x = 52
Check:
Angle 1: x = 52
Angle 2: 2x + 24
2(52) + 24
104 + 24 = 128
128 + 52 = 180
For every c substitute 4 and for every d substitute -2
c=4
d=-2
6c + 5d - 4c - 3d + 3c - 6d
= 6(4)+ 5(-2)- 4(4)- 3(-2)+ 3(4)- 6(-2)
=24+(-10)-16-(-6)+12-(-12)
=24-10-16+6+12+12
=28
