Answer:
x=20 degrees
Step-by-step explanation:
complementary means the angles equal 90 degrees
so ∠A+∠B=90 degrees
∠A=3x-2 and ∠B=x+12
so subsitute
(3x-2)+(x+12)=90
then solve for x
4x+10=90
4x=80
x=20 degrees is your answer
2 wide walls (15x6)x2=180 square feet
2 long walls (25x6)x2=300 square feet
ground 25x15=375 square feet
sum them all up and you get
375+300+180=855
you need paint for 855 square feet
Answer:
c = -2
Step-by-step explanation:
-5c - 10 - 5c - 2 = 8
