I need help getting the answer for the 1st question
Karo-lina-s [1.5K]
If we have two similar triangles:
Triangle 1 (base 1 , height1).
Triangle 2 (base 2, height 2)
Then:

base 1 /height 1=base 2 /height 2

Data:
base 1=0.2 m
height 1= 1 m
base 2= 8 m
height 2=x

We calculate the height of the tower:
base 1 /height 1=base 2 /height 2
0.2 m / 1m=8 m / x
x=(8 m * 1 m) / 0.2 m
x=8 m²/0.2 m
x=40 m

Answer. the heigth of the tower will 40 m

45.7 kilometers =<br> meters
VashaNatasha [74]

Answer:

45.7 kilometers = 45,700 meters

Explanation:

Hi!
Okay, so basically, in one kilometer, there are 1000 meters.
Using this problem, all you have to do is <u>multiply 45.7 by 1000</u>, which is 45,700.

Whatever value is used for kilometers (ex. 2), just multiply by 1000, and you’ll get the value as meters (ex. 2 x 1000 = 2000 meters).


Hope this helps!

I need serious help, I forgot how to do this ;-; I haven't done that kind of math in a long time. How can I find the answer and
larisa [96]

Answer:

I think your answer is 85. The 50 degree angle on the left side of E is equal to the angle to the right of E. Since both triangles have equivalent angle measurements, D and B are correspondent of one another. Add the 50 degrees to the 45 degrees to get 95. Since triangles total measurements equal 180, subtract 95 from 180 to get 85. Angle D = 85, and since Angle B is correspondent, Angle B = 85°
