Find c.
Round to nearest tenth.
c= ? ft.
59.6 is NOT the answer.

Work Shown:

c^2 = a^2 + b^2 - 2*a*b*cos(C)

c^2 = 15^2 + 20^2 - 2*15*20*cos(50)

c^2 = 225 + 400 - 600*cos(50)

c^2 = 225 + 400 - 600*0.642787609686539

c^2 = 225 + 400 - 385.672565811924

c^2 = 239.327434188076

c = sqrt(239.327434188076)

c = 15.470211187572

c = 15.5

y/x of point b= y/x of point a

step-by-step explanation:

(i got the same question, this was the correct answer.)

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)
