Answer 1

Two poles, AB and ED, are fixed to the ground with the help of ropes AC and EC, as shown:

Two right triangles ABC and EDC have a common vertex C. Angle ABC and EDC are right angles. AB is labeled 11 feet, AC is labeled 13 feet, EC is labeled 10 feet, and ED is labeled 5 feet.

What is the approximate distance, in feet, between the two poles?

6.93 feet
8.66 feet
12.32 feet
15.59 feet

Answer 3

15.59 feet

You can simply use the pythagorean theorem. a^2 + b^2 = c^2

Answer 4

the answer is D

Answer 5

Left triangle.
11^2 + b^2 = 13^2
121 + b^2 = 169
b^2 = 48
b= √48
=6.93


Right Triangle
5^2 + b^2 = 10^2
25 + b^2 = 100
b^2 = 75
b = √75
b = 8.66

Add the sides. 6.93+8.66= 15.59
