What is the length of EF in the right triangle below? E 17 13 F A. 458
B. 458
C. 4
D. 1120
E. 30
F. 120

The answer is D. √120

Step-by-step explanation:

Using the pythangorean theorem when solving the missing side of a right triangle, so given a^2 + b^2 = c^2. We have side c, and a so we must rearanged this to fit side b.

So: a^2 + b^2 = c^2 → b^2 = c^2 - a^2 →

b = √(c^2 - a^2).

Given side c or the hypotenuse is 17, and a is 13. side b must have a length of:

√(17^2-13^2) = √(289 - 169) = √120

0

step-by-step explanation:

you can not divide by 0 so 4 ÷ 0 would be 0

0 × 9999 =0

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
