Question

If sin 53 degrees is close to 4/5 , which is closest to the length of /NO
a. 4cm
b. 80cm
c. 20cm
d. 10cm

Answer 1

This is what I got

53 degrees and 37 degrees are the approximate measures of the angles of a 3-4-5 right triangle. The legs have lengths 3 and 4, and the hypotenuse is 5.

The 4 is opposite the larger angle (53 degrees) and the 3 is opposite the 37 degree angle.

sin(53) = opposite/hypotenuse = 4/5

sin(37) = opposite/hypotenuse = 3/5

So I think it is C.
