Answer:
X = 15
Step-by-step explanation:
We move all terms to the left:
<em>x+8+2x-(2x+13)=0</em>
We add all the numbers together, and all the variables:
<em>3x-(2x+13)+8=0</em>
We get rid of parentheses:
<em>3x-2x-13+8=0</em>
We add all the numbers together, and all the variables:
<em>x-5=0</em>
We move all terms containing x to the left, all other terms to the right:
<em>x=5</em>

Answer:
36 (Fill 3 in the blank)
Step-by-step explanation:
Given:
Volume of a cylinder = 324 π
Height = 9 cm
The formula to find the volume of a cylinder = Base area * height.
Base is a circle. So the area of a circle = πr^2
Volume of the cylindrical pillar = πr^2 h
324 π = πr^2 . 9
πr^2 = 324 π /9
πr^2 = 36 π
The area of the base = 36 π
Thank you.

C = 58.84
B = 97.16°
<u>Explanation</u>
The sine rule states:
SinA/a = sinB/b
∴ sin24 / 77 = sinC / 162
sinC = (162 × sin24)/77
= 65.89/77
= 0.85573
C = 58.84°
Angles in a triangle add up to 180°
∴ B + 24 + 58.84 = 180
B = 180 - 24 - 58.84
= 180 - 82.84
= 97.16°
