Example 2: The bottom of a handicap ramp is 15 feet from the entrance of a building. If the angle of the ramp is about 4.8°, how high does the ramp rise off the ground to the nearest inch?


Example 3 what is the value of x to the nearest tenth degree

Example 3: What is the value of x to the nearest tenth degree?


Example 4 find m b to the nearest tenth of a degree if cos b 0 8926 and b is an acute angle

Example 4: Find mB to the nearest tenth of a degree if cosB = 0.8926 and B is an acute angle.
