The hypotenuse of a right triangle is 20 cm. One leg of the triangle is 7 cm. How long must the other leg be? I don’t want the answer in a file

A) 13 cm
B) 21.2 cm
C) 27 cm
D) 18.7 cm

your answer is the frist one

hop i

a reflection across the x axis and a 90 degree rotation left and right.

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
