Answer:
x = 8*root3
y = 16
Step-by-step explanation:
You can use tangent and cosine of 60° to find x and y, BUT THERE'S A SHORTCUT. You pointed out that its a 30°-60°-90° triangle. That is a special right triangle. Here's the shortcut:
the longest side (hypotenuse) is double the shortest side. We have an 8 on the shortest side, so the hypotenuse (longest side) is 16. This ALWAYS works for 30°-60°-90° triangles!
Another shortcut:
The longer leg is the shorter leg × root3.
This ALWAYS works on 30°-60°-90° triangles.
So on your triangle, the short side is 8, that means the longer leg is 8×root3.
ta-daaaa!
153.86 is the answer because the formula is Pi times radius squared. So, the equation would be 3.14X7^2=3.14X49=153.86

Answer:
I believe 2 batteries
Step-by-step explanation:
17.4 pounds from monday + 13.3 from Tuesday= 30.7 pounds.
30.7 pounds times $0.40 is $12.28
12.28/5.5 is 2.327272727...
You cant buy .3 of a batter so the answer should be 2
