Trigonometric Functions

Example 1

Lets assume a = 10 and b = 25

What is the size of the angle x ?

Remember that all the functions return radians so this is converted to degrees in cell "B3".

What is the size of the angle y ?

Remember that all the functions return radians so this is converted to degrees in cell "B3".

Example 2

Lets assume x = 33, y = 57 and c = 18

What is the length of side a ?

What is the length of side b ?
