Answer 1

Use pythagorean theorem
Hypotenuse^2=base^2+perpendicular^2

Answer 2

Here
x^2+x^2=3^2
x=?

Answer 3

Oposit side of 2 equal angles r equal

Answer 4

So in ur triangle
2 oposit side of 2 angles of 45 degree r equal.
x

Answer 5

or cos45 =1/sq.rt(2) =x/3
x=3/sq.rt2

Answer 6

Cos 45=base/hypotenuse=x/3
x=?
