Answer:x=90° y=58° z=32°
Step-by-step explanation:
x=90
y=180-(90+32) sum of angles in a triangle is 180
y=58
y+90+z=180 they are supplementary
58+90+z=180
148+z=180
z=180-148
z=32
ANSWER
B.
EXPLANATION
The volume of a cone is calculated using the formula:
where r=4 units is the base radius of the cone.
and h=21 units is the vertical height of the cone.
We plug in the values to get;
(2,0)
2(2) - 3(0) = 4
10(2) - 15(0) = 20

General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations by substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
y = 3x + 4
y = x + 2
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute: 3x + 4 = x + 2
- Subtract <em>x</em> on both sides: 2x + 4 = 2
- Subtract 4 on both sides: 2x = -2
- Divide both sides by 2: x = -1
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define: y = x + 2
- Substitute: y = -1 + 2
- Add: y = 1
And we have our answer!
