solve the 45-45-90degree triangle for teh unknown sides.

Question

it is a right-angled triangle, it says H on the longest side, LEG on the long leg and LEG=3 on the vertical leg.

inside the top corner it says 45degree and on the left bottom corner it say 45 degree.

Answer 1

IF the vertical side = 3, then the base also =3

and the hypotenuse = sqr(3^2 +3^2) = sqr(18) = 3sqr2 = about 3(1.4) = 4.2

sides are 3,3 and 3sqr2

or 3,3 and about 4.2

Answer 2

The two legs are equal in length.

The hypotenuse is √(2s²)
