Use special right triangle ratios to find the length of the hypotenuse.
45°
18
457
A. 18V3
B. 1872

The length of the hypotenuse is 18√2.
The longest side of the triangle is called as the hypotenuse.
In a right angled triangle, sin 45° = perpendicular /hypotenuse
here, perpendicular side P = 18 units and the hypotenuse H is unknown.
sin 45° = 18 /H
H = 18√2
Thus, the hypotenuse is 18√2.
