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
Answer:
0.025
Explanation:
Divide the percentage by 100 to convert it to decmals.
for example 20%=

.025
Answer:
Step-by-step explanation:
As per diagram, the two triangles are similar, as all angles are congruent (one is vertical, one is right, one is the
Let the distance across the river be x.
<u>The ratio of corresponding sides is same. Find x using ratios:</u>
- x/45 = 75/60
- x = 45*75/60
- x = 56.25 feet
