Answer:

Your answer is :

A rotation Turns a shape. Shapes may be rotated clockwise or Counter-clockwise. Whenever we do a rotation, the figure must stay the same size and the same Shape. It is only turned. Figures always rotate around a Point that does not move. If a figure is rotated all the way around back to where it started, this is called a Full Rotation. Half-way around is 180°.

The area of the following equilateral triangle is 62.4 square feet that is he height
Vikentia [17]

The height of this triangle would be 10.4

In order to find this, you first must find the length of the sides. Using a manipulated formula for area of an equilateral triangle, we can determine the lengths of the side. Below if the formula.

S = \frac{2}{3}3^{\frac{3}{4}} \sqrt{A}

In this, S is the length of the side and A is the area. So we plug in and get:

S = \frac{2}{3}3^{\frac{3}{4}} \sqrt{62.4}

S = \frac{2}{3}3^{\frac{3}{4}} 7.89

S = 12

Now that we have the side as 12, we can use the Pythagorean Theorem to find the height. If you split a equilateral triangle down the middle, you are left with two right triangles. Using this right triangle, the hypotenuse would be 12, the first leg would be 6 (half of the base) and the height would be the other leg. So we plug in and solve.

a^{2} + b^{2} = c^{2}

6^{2} + h^{2} = 12^{2}

36 + h^{2} = 144

h^{2} = 108

h = 10.4

5 4/8 + 1 3/8 =<br> 1. 33/8<br> 2. 55/8<br> 3. 6 7/16
Dovator [93]

Answer: 2. 55/8

Step-by-step explanation: Add the whole numbers first (5+1 = 6), then add the fractions (4/8 + 3/8 = 7/8). Now we have 6 7/8 and since they want the answer in fraction form we will multiply the 6 and the 8 (6x8=48) and then add the 7 to the 48 (7+48 =55) and we leave our answer over the denominator which is 8. This leaves us with the final answer of 55/8
