Pythagorean Formula: c^2 = b^2 + a^2

c^{2} = 3^{2} + 3^{2}

c^{2} = 9 + 9

\sqrt{c^2 = \sqrt{18}

c = 4.242640687 ft - 4.2 ft (Rounded to Nearest Tenth).

When a shape is rotated, it must be rotated around a point.

<em>To determine the location of the new triangle, Sonja must subtract (5,-1) from the coordinates of the original triangle, before rotating by </em>90^o<em>.</em>

<em />

From the question, we have:

C = (5,-1) --- the center of rotation

Let the vertices of the triangle be (x,y).

First, she must subtract the coordinates of the center of rotation from the vertices of the triangle.

This gives:

(x,y) \to (x - 5, y + 1)

Then the vertices are rotated by 90^o

<u />

<u>The rule of </u>90^o<u> rotation is:</u>

(x,y) \to (-y,x)

So, we have:

(x - 5,y + 1) \to (-y - 1,x - 5)

From the attachment, the coordinates of the triangle are: (0,2), (0,5) and (4,2)

After rotation, the coordinates are calculated as follows:

(0,2) \to (-2-1,0-5) \to (-3,-5)

(0,5) \to (-5-1,0-5) \to (-6,-5)

(4,2) \to (-2-1,4-5) \to (-3,-1)

Hence, the coordinates are: (-3,-5), (-6,-5) and (-3,-1)

Sean bought 68 3/4 inches of rope . How many 15-inches ropes can he make from it
choli [55]
Length of rope bought by Sean = 68 3/4 inches
                                                   = 275/4 inches
Then
The number of 15 inch rope that can be made by Sean = (275/4)/15
                                                                                         = 275/(4 * 15)
                                                                                         = 275/60
                                                                                         = 4.58
So we can see from the above deduction that Sean can make 4 complete 15 inches ropes and there will be 0.58 inches of rope excess. <span>I hope the procedure and the method of solving is absolutely clear to you. This is the easiest way to get to the solution for such problems.</span>
