Answer:
-9, -8
Step-by-step explanation:
x+(x+1)=7+3(x+1)
x+x+1=7+3(x+1)
2x+1=7+3(x+1)
2x+1=7+3x+3
2x+1=3x+10
2x+1-1=3x+10-1
2x-3x=3x-3x+9
-1x/-1=9/-1
x=-9/-8
N an acute angle is 90 degrees or less and 90 + 90 is 180 and an obtuse angle is always more than 90 and always less than 180
To fund any volume,you multiply the cross sectional are by the depth of the shape
