Since we have a right triangle, we can relate the angle 28 with x and side 34 by meand of the sine function, that is,


\sin 28=(34)/(x)

where x is the hypotenuse. By moving x to the left hand side, we have


x\cdot\sin 28=34

and by moving sin28 to the right hand side, we get


x=(34)/(\sin 28)

since sin28=0.4694, we have


x=(34)/(0.4694)

then, x is given by


x=72.42

by rounding down, the answer is option D: x=72.4
