How to use the inverse cosine function to find the missing angle of a triangle

👉 Learn how to find a missing angle of a right triangle. A right triangle is a triangle that has 90 degrees as one of its angles. The trigonometric identities of right triangles gives us the relationship between the angles of a right triangle and the side lengths of the right triangle. These trigonometric identities, commonly called SOHCAHTOA, are: sin x = opposite / hypothenuse; cos x = adjacent / hypothenuse and tan x = opposite / adjacent. These identities enables us to find a missing angle of a right triangle given the required side lengths.

This is a great explanation! However, you forgot to mention that your calculator has to be in degrees when calculating, otherwise you'll get a diff answer.

can i find the value without a calculator? or it's impossible?.
