A triangle has sides of lengths 12, 14, and 19. Is it a right triangle? Explain.

a. yes; 12^2 + 14^2* ≠ 19^2
b. no; 12^2 + 14^2 = 19^2
c. no; 12^2+ 14^2 ≠ 19^2
d. yes; 12^2 + 14^2 = 19^2

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316

i believe that the answer is

b. y-1=-2(x-4)

hope this !

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

yes, whats the problem?
