Answer:
Height of second tower = 17.32m
Step-by-step explanation:
I have attached a diagram depicting the question. 
From the diagram, The first tower is depicted by side AEB and the second tower CD. 
While d is the distance that separates the two towers and it's given as 15m.
Now, since the angle of depression of the second tower’s base is 60°, then for triangle BAC. Angle C = 60°.
Thus; using trigonometric ratios;
tan 60° = AB/AC.
This gives; AB = d*tan 60°
Similarly, for the triangle BED, BE = d*tan 30°
Since, AE = CD, thus ;
CD = AB − BE
CD = d (tan 60° − tan 30°)
CD = 15(1.7321 − 0.5774) 
CD = 15 × 1.1547
CD ≈ 17.32 m.
So, height of second tower = 17.32 m
 
        
             
        
        
        
Answer:
The distributive property makes it possible
Step-by-step explanation:
Step one:
given the expression a(b + c ) 
the first step is to open the bracket, that is multiply all the terms in the bracket by a, so multiply b by a and c by a also.
Step two:
Thus, this property is called the distributive property of multiplication
a*b+ca
 
        
             
        
        
        
Answer:

Step-by-step explanation:
We have the four thickest books from the line plot given by 
Two books of  inch thick and the two books of
 inch thick and the two books of  inch thickness.
 inch thickness.
So when the two  inch thick book is being piled on the top of a
 inch thick book is being piled on the top of a  inch thick books.
 inch thick books.
Therefore, the total thickness of the pile of books is given by :



Therefore, the thickness of the pile is  .

Answer:
1/8
Step-by-step explanation:
P(-3, 0) and Y(5,-1)
If PLAY is reflected over x-axis, then P-->P'(-3,0) and Y-->Y'(5,1)
Slope of P'Y' = (1 - 0)/(5+3) = 1/8
