Calculate 7214

Two tangents are drawn from point C to a circle with a radius of 76 mm. The distance between the two contact points is 14 mm. Calculate the distance of point C from the center of the circle.

Correct answer:

x =  76.3244 mm

Step-by-step explanation:

r=76 mm a=14/2=7 mm  a1=r2a2=76272=5727 mm75.6769 mm  x/r = r / a1  x=r2/a1=762/75.6769=76.3244 mm
