One side of a rectangle is 12 yd shorter than three times another side. The area of the rectangle is 756 yd. Find the length of the shorter side.

1. One side of a rectangle is 4 in shorter than three times the other side. Find the sides if the

perimeter of the rectangle is 48 in.

Solution: Let us denote the shorter side by x: Then the other side is 3x

We now apply the zero property. Either x

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

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,
