Evaluate inverse trig functions CCSS.Math: HSF.TF.B.6, HSF.TF.B.7 Google Classroom Microsoft Teams

Inverse trigonometric functions can be helpful for solving equations. For example, if we know that sin (x) = 0.5 , we can use the inverse sine function, sin 1 , to find that x = π 6 or x = 5 π 6 .

Let's find out angle O: angle O is adjacent to line OE, opposite of line ZE, and our hypotenuse is OZ, so you can freely pick between any of the inverse trig functions to answer.
