the third root
Step-by-step explanation:
Check the picture below.
the area of the triangle whose base is AC and height is BD, is the same area of the triangle whose base is AB and altitude is BC, namely

Answer
Find out the how high up the wall does the ladder reach .
To proof
let us assume that the height of the wall be x .
As given
A 25-foot long ladder is propped against a wall at an angle of 18° .
as shown in the diagram given below
By using the trignometric identity

now
Base = wall height = x
Hypotenuse = 25 foot
Put in the trignometric identity


x = 23.8 foot ( approx)
Therefore the height of the ladder be 23.8 foot ( approx) .
Answer: B
Step-by-step explanation: To solve you have to first multiply the number in front of the first pair of () by both numbers inside,then add that together. Then move on the the other pair of (). Multiply those together. Take the two numbers that you now have and add those to get the final answer.
