Question

find the other two side

Answer 1

hello mate.here is your answer..


hope it helps you

Answer 2

let the altitude is x

therefore base = x +7

we know in right angle triangle ,
by Pythagoras theorum

hypotenuse ^2 = base ^2 + altitude ^2

13 ^2 = x^2 + ( x+7)^2

169 = x^2 + x^2 +14x + 49

2x^2 + 14x + 49 - 169 = 0

2x^2 + 14x - 120 = 0

x^2 + 7x - 60 = 0

x^2 + 12x - 5x - 60 = 0

x ( x + 12 ) -5 ( x+12) = 0

( x + 12 ) (x -5) =0


( x + 12 ) =0 or (x -5) =0

x = -12 or x =5

side never negative

therefore , altitude =5 cm

base = 5+7 = 12 cm
