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

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

well the answer to that is xoxoxo

step-by-step explanation:
