A pole that is 3m tall casts a shadow that is 1.22m long. At the same time, a nearby building casts a shadow that is 38.5m long.
vichka [17]
Refer to the diagram shown below.

The height of the pole is CD (3 m), and its shadow is AB (1.22 m).
The height of the building is h m, and its shadow is AD (38.5 m).

The two triangles ΔABC and ΔADE are similar because of AAA.
Therefore
\frac{DE}{BC} = \frac{AD}{AB} \\\\  \frac{h}{3} = \frac{38.5}{1.22}

Cross multiply.
1.22 h = 3*38.5 = 115.5
h = 115.5/1.22 = 140.91 m

Answer: 141 m (nearest meter)

Helppp!!!! please!!!
zheka24 [161]

Answer:

D. 104

Step-by-step explanation:

We know that xy and yz are supplementary to each other

That means they add up to 180

We can set up an equation with this information

(4x+32)+(2x+40)=180

6x+72=180

6x=108

x=18

Now that we know what x is, we can plug it into 4x+32 to find degree of xy

4(18)+32

72+32

D. 104
