The equation sin(25o) =9/c can be used to find the length of ab .
what is the length of ab? round to the nearest tenth.

c = 9/sin(25)

c = 9/0.4226

c = 21.2958

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
