Answer:
x=31.4
Explanation:
From the given diagram , x is the hypotenuse
angle is 35 degree
we are given with opposite side length is 18
WE use trigonometric ratio sin

opposite side = 18
hypotenuse is x
angle is 35

Multiply both sides by x and then divide both sides by sin(35)

use calculator to find out x
x=31.3804
Round to nearest tenth
x=31.4
