Correct option is A
The elevation (height) for a specific angle using a sine bar can be calculated using the formula:
Height(h) = Sine of angle × Length of the sine bar
Given:
Angle = 30°
Length of the sine bar = 5.00 inches
Height (h) = sin (30°) x 5.00 inches
Height(h) = 0.5 x 5 inches = 2.5 inches
So. the elevation for 30° using a 5.00" sine bar is 2.5000".
