Inverse Trigonometric Functions

We can use inverse trigonometric functions to find an angle with a given trigonometric value. We can also inverse trigonometric functions to solve a right triangle.

Examples:

1. Use the calculator to find an angle θ in the interval [0, 90] that satisfies the equation.
   a) sin θ = 0.7523
   b) tan θ = 3.54
2. Solve the given right triangle if a = 44.3 cm and b = 55.9 cm
3. Find each angle in a 3, 4, 5 right triangle.
