Activity You will use GeoGebra to practice using trigonometric functions and their inverses. Go to inverse trig functions e, and complete each step
below.
Question 1
Click the refresh button until you get a right triangle with ZA as the right angle. Fill in the fraction forms of sin B, cos B, tan B and then the
associated measure of ZB using sin, cos!, and tan', rounded to three decimal places each. Then fill in the fraction forms of sin C, cos C, tan C
and the associated measure of LC using sin", cos!, and tan rounded to three decimal places.
