Answer:

Option A

Step-by-step explanation:

In the given right angle triangle ABC,

BC = 15 m and m∠A = 55°

We have to calculate the measure of side AC.

Since tanA = $\frac{Height}{Base}$

tan55 = $\frac{15}{AC}$

1.428 = $\frac{15}{AC}$

1.428(AC) = 15

AC = $\frac{15}{1.428}$

AC = 10.5 m

Therefore, Option A. AC = 10.5 m is the answer

The diagram below shows a circular pizza with a diameter of 10 inches. The pizza is in a square box with side lengths of 12 inch

rodikova [14]

Answer: 65.5 inches of the box is empty.

Step-by-step explanation:

Given : Diamter of circular pizza =10 inches

Then, radius = $\dfrac{10}{2} = 5\text{ inches}$

Area of circle = $\pi r^2$

Area of pizza = $3.14\times(5)^2=78.5\ sq. inches.$

Side of square = 12 inches

Area of square = side x side.

Area of square = 12 x 12 = 144sq. inches.

Area of box empty = Area of square - Area of pizza

= 144-78.5 sq. inches

= 65.5 inches

Hence, 65.5 inches of the box is empty.
