in abc the measure of angle a is 2x+3, the measure of b is 4x+2, the measure of c is 2x-1. What are the measures of the angles?

Mama L [17]

The measures of the angles in a triangle add up to 180°.
$2x+3+4x+2+2x-1=180 \\
8x+4=180 \ \ \ |-4 \\
8x=176 \ \ \ |\div 8 \\
x=22 \\ \\
2x+3=2 \times 22+3=44+3=47 \\
4x+2=4 \times 22+2=88+2=90 \\
2x-1=2 \times 22-1=44-1=43$

The measures of the angles are 43°, 47° and 90°.

You have a cylinder-shaped bottle that you want to fill with sand. The diameter of the bottle is 5 inches and the height is 15 i

emmainna [20.7K]

Answer:

Step-by-step explanation:

The volume of a cylinder is

$V=\pi r^2h$

We are given a diameter of 5, which means that the radius is 2.5. The height is 15. Filling in:

$V=\pi(2.5)^2(15)$

which gives you, in terms of π:

V = 93.75π in³ or if you are multiplying in π,

V = 294.5 in³
