Answer:
x = 10
Step-by-step explanation:
See image. Due to the logic of vertically opposite angles (when one angle is equal to the other that is "vertically opposite" to it), the two angles that I have marked in the diagram are going to equal.
Therefore, if we were to write it out:
2x + 7x = 90
(vertically opposite angles)
9x = 90
∴ x = 10

Given:
Radius of a cylinder = 5 units.
Surface area of the cylinder =
To find:
The height of the right cylinder.
Solution:
Surface area of a cylinder is:
Where, r is radius and h is the height of the cylinder.
Putting in the above formula, we get
Subtract from both sides.
Divide both sides by .
Therefore, the height of the cylinder is 11 units.
