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) .
Being in love/caring for someone clouds your judgement causing you to overlook their faults. however, once the "rose colored glasses" come off you start to recognise where they were wrong.

Answer:
15
Step-by-step explanation:
50 * .30=15
3, 12, 15, 25, 30, 40The range is the difference between the greatest and smallest values:
range = 40 - 3 = 37
Thee average is the sum of elements divided by the number of elements:
average = (<span>3 + 12 + 15 + 25 + 30 + 40</span>)/6
average = 125/6 = 20.83
