Answer:

Hey there!

First, we want to find the side length of the large triangle.

1/2bh=y cm^2

bh=2y cm^2

Since b and h are the same here, we have b^2= 2y, b=\sqrt{2y}.

And we have FC=\frac{\sqrt{2y} }{2}.

Area of shaded triangle: \frac{1}{2} (\frac{\sqrt{2y} }{2})(\frac{\sqrt{2y} }{2}).

This is equal to: \frac{1}{2}(\frac{2y}{4}), or y/4.

Let me know if this helps :)

25 + 17 = E + 2
42 = E + 2
42 - 2 = E
40 = E <== there are 40 edges

Selam purchased a pen at 20% discount on marked price but sold it at marked price find the grain per cent of the Saleem on the t
kiruha [24]

Answer:

25%

Step-by-step explanation:

let the Market Price of the Watch (M.P.) be x

CP for Rahim=x-[(20/100)*x]

CP = (1 *x) /5 = 4x/5

SP for Rahim = MP = x

Difference (Profit) = SP-CP = x - (4x/5) = (5x - 4x)/5 = x/5

Profit % = (Profit/CP) * 100

Profit % = (x/5)/(4x/5) * 100

Profit % = 25 %
