Jared is constructing a rectangular door for a shed. if the door, shown below, has a width of 42 in. and a diagonal support of 94 in., what is the approximate height of the door? a. 136 in. b. 84 in. c. 52 in. d. 103 in.

B

Step-by-step explanation:

A rectangular door for a shed has a width of 42 in and a diagonal support of 94 in. The triangle formed by the rectangle's width (first leg), rectangle's length (second leg) and rectangle's diagonal (hypotenuse) is right triangle. By the Pythagorean theorem,

Thus,

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
