<u>Given </u>that the length of the hypotenuse is x and the angle is 53°
The length of one of the leg of the triangle is 45.
We need to determine the value of x.
<u>Value of x:</u>
The value of x can be determined using the trigonometric ratio.
Thus, we have;
Substituting the values, we get;
Simplifying the terms, we have;
Dividing, we have;
Therefore, the value of x is 74.77(app)
Hence, Option B is the correct answer.
