ANSWER

The length of the shadow is 49 ft to nearest feet.

EXPLANATION

We can find the length of the shadow using the tangent ratio.

Recall that,

\tan(27 \degree) = \frac{opposite}{adjacent}
From the diagram, the length of the shadow is the side of the triangle that is adjacent to the 27° angle

\tan(27 \degree) = \frac{45}{adjacent}

This implies that,

adjacent = \frac{45}{tan27 \degree}

adjacent = 49 .065
