On a sunny day a telephone pole cast a shadow that is 10 feet long at the same time 36 inch yardstick cast a shadow that is 15 i
1 answer:
Answer:
The height of the telephone pole is 24 feet.
Step-by-step explanation:
The same rays are falling on the pole and yardstick, so at the same time of day both pole and yardstick have same angle of elevation from the ground.
<em>The height of yard stick is 36 inch and shadow is 15 inch long.</em>
<em>Let the height of pole be "x" , with shadow 10 feet long.</em>
1 feet = 12 inches
The 2 triangles are similar. Thus,
<em></em>
<em>x = 288 inches = </em>
Thus, the height of telephone pole is 24 feet.

The value of the cosine ratio cos(L) is 5/13
<h3>How to determine the cosine ratio?</h3>The complete question is added as an attachment
Start by calculating the hypotenuse (h) using
h^2 = 5^2 + 12^2
Evaluate the exponent
h^2 = 25 + 144
Evaluate the sum
h^2 = 169
Evaluate the exponent of both sides
h = 13
The cosine ratio is then calculated as:
cos(L) = KL/h
This gives
cos(L) =5/13
Hence, the value of the cosine ratio cos(L) is 5/13
