a pole that is 3.3 M tall casts a shadow that is 1.22 M long at the same time a nearby Tower cast a shadow that is 50.75 M long
jenyasd209 [6]
Since there is no distance between the pole and the base of the tower, we can assume that the pole is at the base of the tower. 
We can create a right triangles between the pole and its shadow and between the tower and its shadow as shown in the figure. Let x be the height of the tower. Since our triangles are similar the ratio between its sides is going to be proportional, so we can establish a proportion to find x:
\frac{x}{3.3} = \frac{50.75}{1.22}
x= \frac{(50.75)(3.3)}{1.22}
x=137.27

We can conclude that the tower is 137.27 meters tall.

The sum of two numbers is 122. The difference of the first number and twice the second number is 23. Find the two numbers.
Elza [17]

Answer:

One is 89 , the other is 33.

Step-by-step explanation:

Set up a system of 2 equations:

x + y = 122

x - 2y = 23        Subtracting:

0 + 3y = 99

y = 33.

So:

x + 33 = 122

x = 122 -33 = 89.
