No, these are not equal, here's why:
3 * 5 = 15
7 * 5 = 35
7 * 5 ≠ 45

Another good way to look at it is in fraction form:

3/7 is simplified
15/54 = 1/3
1/3 ≠ 3/7

So, in conclusion, these are not complementary ratios

Hope this helps.

What is the value of x in the triangle?

Arturiano [62]

We can use SOH CAH TOA to solve this :)

We’re going to use Cosine because the angle and sides given are Adjacent and Hypotenuse- which goes with the CAH part of SOH CAH TOA.

Cos(18) = x/25

Multiply both sides by 25

25cos(18) = X = 23.776

So x = 23.776 cm

I hope this Helps!
