Two pillars of height 70 m 20 m are standing 120m apart find distance between their tops​

Answer»

Step-by-step EXPLANATION:

Two pillars of HEIGHT 70m and 20 m are standing apart . If distance between their feet is 120m , the distance between their tops is 130 m

Step-by-step explanation:

The distance between the pillars = 120 m

The difference in the height of the pillars = 70 - 20 = 50 m

Let the distance between their tops be x

The by PYTHAGORAS Theorem

x^2=120^2+50^2x

2

=120

2

+50

2

\implies x^2=14400+2500⟹x

2

=14400+2500

\implies x^2=16900⟹x

2

=16900

\implies x^2=169\times 100⟹x

2

=169×100

\implies x=\sqrt{169\times 100}⟹x=

169×100

\implies x=13\times 10⟹x=13×10

\implies x=130⟹x=130 m

Hope this HELPS.
