A.) math- 45, science- 20, social studies- 18, language arts- 17

b.) math- 33.8, science- 15, social studies- 13.5, language arts- 12.8

I’m not sure about b. If you round to the nearest tenth, you get 75.1, but if you keep them as they come out on the calculator, they add up to 75.

Please help meeeeee ://
a_sh-v [17]
A). They are supplementary angles meaning they add up to 180
So
B) (12x+8)+(3x+7)=180
12x+8+3x+7=180
15x+15=180
-15 -15
15x=165
15/15x=165/15
x=11

Angle 1 is
12x+8
12(11)+8
132+8
140
Therefore measure of angle 1 is 140°

Angle 2
3x+7
3(11)+7
33+7
40
Measure of angle 2 is 40°
