Explanation

To get a:c, multiply the two ratios together so the b cancels out.

a:c = (a/b) × (b/c) = 12/13 × 8/9 = 96/117.

96 and 117 can both be divided by 3, which gives 32/39.

So a:c = 32:39.

Explanation

Add them up and divide by how many numbers there are.

16 + 18 + 20 = 54  

54 ÷ 3 = 18

So the mean is 18.

Explanation

cosecθ is just 1 over sinθ.  

So sinθ × cosecθ = sinθ × (1/sinθ) = 1.

The sinθ cancels out, and you’re left with 1.

Explanation

If sinθ = 9/41, use the identity sin²θ + cos²θ = 1.

First find sin²θ: (9/41)² = 81/1681.  

Then cos²θ = 1 - 81/1681 = 1600/1681.  

Take the square root and you get cosθ = 40/41.
