13. - 4/5
14. 11/25
16. 8/9
I don’t know what is an answer of 17 sorry...:(
Think of it this way:
3600 divided by 2 is 1800
and 6 divided by 2 is 3.
Since both the dividend and the divisor were divided by 2, the quotient is the same for both because the ratios were the same.
<u>
</u><u>3600</u> = <u>1800
</u> 6 3
cross multiply
10,800=10,800
The quotients are the same (600).

410+48=458
Answer: 
======================================================
Explanation:
Method 1
We can use the pythagorean theorem to find x.

-----------------------------------
Method 2
Use the sine ratio to find x. You'll need a reference sheet or the unit circle, or simply memorize that sin(60) = sqrt(3)/2

-----------------------------------
Method 3
Similar to the previous method, but we'll use tangent this time.
Use a reference sheet, unit circle, or memorize that tan(60) = sqrt(3)

-----------------------------------
Method 4
This is a 30-60-90 triangle. In other words, the angles are 30 degrees, 60 degrees, and 90 degrees.
Because of this special type of triangle, we know that the long leg is exactly sqrt(3) times that of the short leg.

The short leg is always opposite the smallest angle (30 degrees).
