What is the length of b rounded to the nearest tenth? http://static.k12.com/eli/bb/598/-1/0/2_40666_55141/-1/dc80263c07e2d5e4a7c782b8502ddce71aae8595/media/dce6c717f861f830f08192cfd88cce1b4af8099e/mediaasset_1304964_1.png

Answer 1

hi,
It's basic trigonometry
use a scientific cal and ....
if there is an angle (x) in a right angle triangle (x not equal to 90)
sin x = length of the side opposite to the angle/length of hypotenuse

So
length of the side opposite to the angle = sin (x) * length of hypotenuse

here;
sin x = sin 32
length of the side opposite to the angle = b
length of hypotenuse = 15

hope this will help ya out !
