Question

in triangle DEF, DE=17 and measurment of F= 32. find DF to the nearest tenth.

Answer 1

I assume this is a right triangle with angle E the right angle. So,

we will use the trig function sine to solve it.

sin 32 = 17/x (where x is DF the hypotenuse.)
x = 17/sin32
x = 17/ .5514
x = 30.8 (approx.)
