A surveyor needs to measure the​ distance, AB, across the lake. Beginning at​ E, he locates the​ midpoint, C, of and the​ midpoint, D, of . He then measures . What is​ AB? In triangle ABE, point C is on line segment AE and point D is on line segment BE. Line segments BD and DE each have a tick mark. Line segments AC and CE each have two tick marks. Line segment CD is also shown and has length 60 meters. Part of this figure is above a lake. Line segment AB shows the width of the widest part of the lake. Line segment CD is at the left edge of the lake.
60 m

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.

step-by-step explanation:

b. hoped i'm right lol

step-by-step explanation:

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.

236 cm 16 time 12 = 192

6 times 7 = 42

192+42
