Answer:
Length = 20 inches
Area = 300 inches
Step-by-step explanation:
<em><u>TO FIND THE LENGTH</u></em>
Pythagorean Theorem: 15 squared + x squared = 25 squared
= 225 + x squared = 625
- 225 - 225
= x squared = 400
find square root
= x = 20 inches
x = 20 inches
Length = 20 inches
<u><em>TO FIND THE AREA</em></u>
length x width
length = 20 inches
width = 15 inches
20 x 15 = 300
Area = 300 inches
X^2 + 6x = 13
x^2 + 6x + 9 = 13 + 9
(x + 3)^2 = 22
x + 3 = (+,-) sq rt 22
x = -3 + (sq rt 22) and x = -3 - (sq rt 22)
The height of the fence is irrelevant. The bottom of the ladder is 3+8 = 11 feet from the building. The window is 14ft above the ground:
sqrt(14^2+11^2) = length of your ladder.
