Well you can start by drawing a triangle with the information
the size of angle B can be found using the Law of Sine
the size of angle C can be found using angle sum of a triangle.
The length of side c can be found using the Law of Cosines
hope it helps

➷ You can form this equation:
(call the unknown number x)
8x - 66 = 2x
Add 66 to both sides:
8x = 2x + 66
Subtract 2x from both sides:
6x = 66
Divide both sides by 6:
x = 11 <== this is the number

Answer:
Large Jar : £1.54÷440g= 0.0035
Small Jar : £1.26÷340= 0.0037058
0.0035<0.0037058
Large Jar is the best value.
Answer:
double the radius.
Step-by-step explanation:
Quadruple means 4 times. So you want to make the volume 4 times larger than it currently is.
This can be a little nasty because both numbers are the same.
V = 1/3 pi * r^2 * h
V = 1/3 3.14 * 4.8^2 * 4.8
V = 115.75296
Now if you double the radius, the volume becomes 4 times larger (or it should)
V= 1/3 * 3.14 * (9.6)^2 * 4.8
V = 463.012
Did that make the original volume larger?
115.75296 * 4 = 463.012 rounded.
Hello,
First, sin(x) = O/H
Next, sin(x) ->> x = sin^-1(O/H)
Last, x = sin^-1(142/284) = 30°
30° makes sense because this scenario of a drawbridge creates a 30-60-90 triangle.
Good luck to you! Any questions, ask away.
