Answer:
Therefore, height of the wall at which the ladder is placed is AB = 39.12 foot.
Step-by-step explanation:
Let,
AB = height of the wall at which the ladder is placed
AC = height of the ladder = 40 foot
BC = distance from the wall to the base of the ladder = 8 feet
To Find:
AB = height of the wall at which the ladder is placed = ?
Solution:
Consider a right angled triangle Δ ABC right angle at angle B,
So by Pythagoras theorem we have
AC² = AB² + BC²
Substituting the given values in above equation we get
40² = AB² + 8²
∴ AB² = 40² - 8²
∴ AB² = 1536
Therefore, height of the wall at which the ladder is placed is AB = 39.12 foot.

Answer:
n=25
Step-by-step explanation:
so you take 12.5 divide that by 0.5
and your answer would be 25
The scale of the smaller rectangle is 1/2 of the larger.
Divide each measurements by 2
36/2 = 18
<em>length = 18 cm
</em><em>
</em>28/2 = 14
<em>width = 14 cm</em>
A = length x width
A = 18 x 14
A = <em>252</em> <em>cm</em><em /><em>²</em>
