Question

If you are using Cosine and need to solve for an unknown hypotenuse, you should...

Answer 1

Using cosine, we can find the hypotenuse by using the formula below;

hypotenuse = adjacent / cos ∅

Trigonometric ratios:

• Trigonometric ratios are ratios of sides of a right angled triangle.
• The simplest ratios are cosine, sine and tangent.

Using cosine, the hypotenuse side can be solved as follows:

cosine ∅ = adjacent / hypotenuse

cross multiply

hypotenuse cos ∅ = adjacent

divide both sides by cos ∅

hypotenuse cos ∅ / cos ∅ = adjacent / cos ∅

Therefore,

hypotenuse = adjacent / cos ∅
