Answer:
A. 85°
Step-by-step explanation:
By interior angle sum theorem of a triangle.
x = 180° - ( 40° + 55°)
x = 180° - 95°
x = 85°
Assuming the cylinder is closed at both ends
Surface area = 2 pi r^2 + 2 pi r h = 108
now h = r/2 so we have:-
2pi r^2 + pi r^2= 108
3 pi r^2 = 108
r^2 = 11.459
r = 3.385
so the height h = 1.693 m to nearest thousandth
Answer:one solution
Step-by-step explanation:
x=-3, TeR
x=2.5
Step-by-step explanation:
x+3.5/4=2(2x+2)/4
x+3.5=2x+2/2
x-2x+3.5=1
-x=(-3.5)+1
-x=(-2.5)
-x/(-1)=(-2.5)/(-1)
x=2.5
