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 two triangles are similar.<br> What is the value of x?<br> Enter your answer in the box.<br> X=

fomenos

Answer:

Step-by-step explanation:

In similar triangles, the corresponding sides are in same proportion.

$\sf \dfrac{4x}{3x+1}=\dfrac{15}{12}$

Cross multiply,

4x*12 = 15*(3x + 1)

48x = 15*3x + 15*1

48x = 45x + 15

48x -45x = 15

3x = 15

x = 15/3

x = 5

– 4/5 (9x – 20) – 3x = 4/5 x – 6. Enter the value of x that makes this equation true.

marta [7]

- 4/5*9x +4/5*20 - 3x= 4/5x- 6
-36/5*x+16-3x-4/5*x= -6
-36/5*x-15x/5-4/5*x=-6-16
-55/5*x=-22
-11x= -22
x= -22:(-11)
x=2

-4/5(9*2-20)-3*2=4/5*2-6
-4/5*(-2)-6=8/5-6
8/5-6=8/5-6
