One leg of a right triangle is 10 units, and its hypotenuse is 12 units. What is the length of the other leg? A. about 7 units B. about 15 units C. about 25 units D. about 122 units E. about 224 units

A

Step-by-step explanation:

We can use the Pythagorean Theorem:

, where a and b are the two legs and c is the hypotenuse.

Plug in what we know:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
