Answer:
A=40, B=60, C=80
Step-by-step explanation:
180/7 to find what "1" would be in the ratio then multiply 20*2, 20*3, 20*4.
The measures of the angles in a triangle with the ratio 2:3:4, namely ∆ABC, are 40°, 60°, and 80° respectively.
To determine the measures of the angles in ∆ABC given that m∠A: m∠B: m∠C = 2:3:4, you first need to understand that the sum of the interior angles in a triangle equals 180°.
We will begin by assigning values to the angles as per the given ratios.
Therefore, we'll say m∠A = 2x, m∠B = 3x, and m∠C = 4x.
Based on the rule that the angles of a triangle add up to 180°, we get the equation 2x + 3x + 4x = 180.
Simplifying that, we get 9x = 180.
To find the value for 'x', divide both sides of the equation by 9. This results to x = 20.
To get the measures of the angles, you then multiply the values of 'x' with the ratios.
Hence, m∠A = 2 * 20 = 40°, m∠B = 3 * 20 = 60°, and m∠C = 4 * 20 = 80°.

Answer:
V = 18 pi unit ^3
Step-by-step explanation:
Volume of a cylinder is given by
V = pi r^2 h
where r is the radius and h is the height
V = pi * (3)^2 *2
V = pi *9(2)
V = 18 pi unit ^3
The volume of a cylinder is
(Pi) x (radius squared) x (height) .
Using this, you can FIND the volume of any cylinder, even when you don't know it. This one is 18 pi cubic units.
