Step 1
<u>First situation</u>
when a ladder is leaning against a wall
Let
x-------> the distance of the bottom of the ladder from the wall
L-------> the length of the ladder
<u>Find the length of the ladder</u>
Applying the Pythagorean Theorem
------> equation
Step 2
<u>Second situation</u>
when the ladder will be lying flat on the ground
<u>Find the length of the ladder</u>
In this situation the length of the ladder is equal to
square both sides
------> equation
Step 3
equate equation and equation
therefore
<u>the answer is</u>
the length of the ladder is
see the attached figure to better understand the problem
11. 7, or -1
you are setting it so it's equal to 0
There is no work being done. You just need to set one or both equations up so it equals 0
0(x) will always be 0
D) Not similar as every sides and angles of triangle are not equal to the sides and angles of other triangle
Answer:
The value of y is 3 cm.
Step-by-step explanation:
Given,
Perimeter of triangle =
Solution,
Lets redraw the triangle with nomenclature ABC, given in the attachment.
∴P(ΔABC) = 29 cm (P stands for perimeter)
Length of AB =
Length of BC =
Length of CA =
Now, we all know that the perimeter of a triangle is sum of all the three sides of triangle.
P(ΔABC) = Length of AB+Length of BC+Length of CA
On substituting the values, we get;
Length of AB =
Length of BC =
Length of CA =
Hence the value of y is 3 cm.
