Answer:
The length of the ladder = 6.5077 ft
Step-by-step explanation:
Given A ladder leans against the side of a house
Given the angle of elevation of the ladder is 66° when the bottom of the ladder is 16 ft from the side of the house
<em>Let 'C' be the point of observation.</em>
Given CA= 16 ft
<em> From right angle triangle</em>
<em> </em>
x = 16 × cos 66°
x = 16 × 0.4067
x = 6.5077
<em> x = 6.5 ft</em>
<em>The length of the ladder = 6.5 ft</em>
B. the weight of the objects inside the box
Answer:
Option (4)
Step-by-step explanation:
To calculate the volume of a pyramid we use the formula,
V = 
Area of the square base = (Side)²
= (6)²
= 36 square ft
Height of the pyramid 'h' = 
[By Pythagoras theorem]
h = 
h = 
h = 4 ft
Therefore, volume of the given pyramid = 
= 48 cubic ft
Option (4). 48 ft³ will be the answer.
Answer:
extraneous
Step-by-step explanation:
extraneous
Use the Pythagorean theorem
20^2+47^2 must equal 52^2 for the triangle to be a right triangle. Hope this helps!
