Answer:

Answer:

x = 12.5

Step-by-step explanation:

The 3 angles lie on a straight line and so sum to 180°, that is

x + 10 + 10x + x + 20 = 180, simplify

12x + 30 = 180 ( subtract 30 from both sides )

12x = 150 ( divide both sides by 12 )

x = 12.5

HELP ME PLEASE!!! best answer gets brainliest show steps please​
solniwko [45]

Answer:

height = 20 cm

Step-by-step explanation:

The volume (V) of a cylinder is calculated using the formula

V = πr²h ← r is the radius and h the height

given r = 12 and V = 2880π, then

π × 12²h = 2880π

144πh = 2880π ( divide both sides by 144π )

h = \frac{2880\pi }{144\pi } = 20
