The equation sin(40o) = can be used to determine the length of line segment ac. what is the length of ? round to the nearest tenth.

The
For more explanation please look at the image.
according to the image, the length of line segment AC can be found as
the following method shows:

sin(40°)= opposite side  / hypotenuse,  opposite side = b, hypotenuse = AB= 20cm
sin(40°)= b / 20 and this applies, b = 20 x sin(40°) = 0.64*20 = 12.85 cm
AC= 12.85 cm

 

Idk idk idk idk idk idk idk idk
