Geom. Chap 10: 2 tangents to circle for 90-deg angle; circle's radius r=8; find....

[GreenKnight00]

The Measure of an angle formed by two tangents to a circle is 90. If the radius of the circle is 8 centimeters, how far is the vertex of the angle from the center of the circle?

A)8 cm B) 8√ 2 cm C) 8√ 3 cm D) 16 cm

(there should be an attachment of my work)

Use Pythagoras's theorem and calculate the hypotenuse.

If the length of the leg of an isosceles right triangle is \(\displaystyle s\) then what is the length of the hypotenuse?
