The option that represents cos M is MN / MO
Using trigonometric ratios, we can find the ratio of sides of a right angle triangle.
Trigonometric ratios:
- sin x = opposite / hypotenuse
- cos x = adjacent / hypotenuse
- tan x = opposite / adjacent
Therefore,
cos M = adjacent / hypotenuse
cos M = MN / 0M
Therefore, cos M = MN / MO
