Bill measures the circumference of a circular fish pond to be 28 ft. What is the diameter of the fish pond, rounded to the neare

zalisa [80]

It would be 9 ft. using the knowledge of $\pi$ times the diameter ( $\pi$ equals aprox. 3.14) equal the circumference of a circle, and since we know the circumference, we need to divide that by $\pi$ to get the diameter.

equation: 28/3.14=8.913
rounding that would bring it to 9 ft.

In ΔBCD, the measure of ∠D=90°, the measure of ∠C=42°, and CD = 7.5 feet. Find the length of DB to the nearest tenth of a foot.

Whitepunk [10]

We have been given that in ΔBCD, the measure of ∠D=90°, the measure of ∠C=42°, and CD = 7.5 feet. We are asked to find the length of DB to nearest tenth of foot.

First of all, we will draw a right triangle using our given information.

We can see from the attachment that DB is opposite side to angle C and CD is adjacent side to angle.

We know that tangent relates opposite side of right triangle to adjacent side of right triangle.

$\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}$
