Answer:
5 Miles
Step-by-step explanation:
Given, Height of the tower is 3 miles and the distance from the base is 4 miles.
According the Pythagoras Theorem, the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.
So, putting the data in Pythagoras theorem, let's consider A= 3 and B= 4.
So C will be,
sqrt(A^2 + B^2 )= C
Or, sqrt( 3^2+ 4^2)= C
Or, sqrt( 9+ 16) = C
Or, sqrt(25) = C
Hence, C = 5
So, The distance would be 5 Miles.
Answer:
a)1 : 4 and 5 : 20
Step-by-step explanation:
If a ratio is a proportion that means the
quantity on the left hand side is lesser than the quantity on the right hand side; it's a part of a whole, a small fraction.
Example of proportion ratios:
4 : 7
7 : 29
90 : 200
68 : 140
Example of non-prpotion ratios:
7 : 4
80 : 19
29 : 20
