Question

Patricia has a lawn, ABCD. She has placed a watering hose, BD, as shown below.



Part A: Patricia plans to put a fence along the length AD of her lawn. What is the length of the fence required?
Part B: Using complete sentences, explain how you arrived at the answer for Part A.

Answer 1

a fence along the length AD of her lawn. You need to find the length of AD.

Answer 2

do you know about 30 60 90 triangles?

Answer 3

Yes

Answer 4

do you pythagorean theorem? use it to find BD

Answer 5

What do you mean how do we use that here?

Answer 6

First find BD

Answer 7

How?

Answer 8

oh wait i see now!

Answer 9

sorry the angle was confusing me

Answer 10

in a right triangle (one with a 90 angle) with sides a,b,c
where c (hypotenuse) is the longest side:
a^2+b^2= c^2

Answer 11

c=34

Answer 12

so what do you know about 30-60-90 triangles? or do you know trig?

Answer 13

In 30-60-90 triangle, the length of the hypotenuse is twice the length of the leg opposite the 30 degree

Answer 14

the leg opposite the 60 degree angle is sqrt3 as long as the leg opposite the 30 degree. That's pretty much all i know
