Using Trig to Find Missing Angles and Missing Sides

Finding a missing side. (Figuring out which ratio to use and getting to use a trig button.)

Ex: 6. Figure out which ratio to use. Find x Ex: 6 Figure out which ratio to use. Find x. Round to the nearest tenth. 20 m x A O

Ex: 7 Find the missing side. Round to the nearest tenth. 80 ft x O A

Ex: 8 Find the missing side. Round to the nearest tenth.

Ex: 9 Find the missing side. Round to the nearest tenth. 20 ft x A

When we are trying to find a side we use sin, cos, or tan. When we are trying to find an angle we use (INVERSE) sin-1, cos-1, or tan-1.
