Question

Solve the following​

Answer 1

Answer:

THIS IS THE ANSWER MARK AS BRAINLIAST

Answer 2

Step-by-step explanation:

OK SOO

let one side be x

other is 3x+3

1/2×b×h=84

1/2×(x)×(3x+3) =84

3x^2+3x=168

3x^2+3x-168=0

dividing eq by 3 to simplify it

x^2+x-56=0

x^2+8x-7x-56=0

x(x+8)-7(x+8)=0

(x-7)(x+8)=0

x=7

x=-8(rejected)

So x= 7cm

other side =3x+3 =24cm

So you can find the hypotenuse by pythagoras theorm and it will be 25 cm

hope it helps
