First you have to change 12 mm to cm, which would be 1.2 cm. The formula for the volume of a triangular prism is 1/2 x a x c x h. So, 1/2 (2.5) x (1.2) x (2.5) = 3.75 cm^3

Two angles are supplementary one of them is 24 more than twice the other how large is the other angle

Advocard [28]

Answer:

Angle 1: 52 degrees

Angle 2: 128 degrees

Step-by-step explanation:

Angle 1 = x

Angle 2 = 2x + 24

Supplementary angles are two angles that add up to 180 degrees.

x + 2x + 24 = 180

3x + 24 = 180

3x = 180 -24

3x = 156

x = 52

Check:

Angle 1: x = 52

Angle 2: 2x + 24

2(52) + 24

104 + 24 = 128

128 + 52 = 180

I will give a brainliest to the person who has gets the correct answer with an explanation of how you solved it.

Answer: $V = 24,416.64m^{3}$

Step-by-step explanation:

Solve for v by simplifying both sides of the equation, then isolating the variable.

Formula: $v = \frac{4}{3} \pi r^{3}$

Plugin the variable: $v = \frac{3}{4}\pi (18^{3})$

Solve:

$v = \frac{4}{3} 3.14 (5,832)$

$v = 4.18666666(5,832)$

$V = 24,416.64m^{3}$
