If the legs are legnth x, then the hyptonuse is x√2

x√2=7
divide both sides by √2
x=7/√2
times (√2)/(√2)
(7√2)/2

Can anyone help. Greatly appreciate:)

Answer:

Area= 12 units squared, Perimeter= 16.12899

Step-by-step explanation:

AC= \sqrt{(4-0)^{2}+ (0+4)^{2}} = 4\sqrt{2}

AB= \sqrt{(0-4)^{2}+ (2-0)^{2} } = 2\sqrt{5}

BC= \sqrt{(0-0)^{2}+ (2+4)^{2} }= 6

So, perimeter= 4\sqrt{2} + 2\sqrt{5} +6= 16.12899

Area= \frac{1}{2}bh\\

        = \frac{1}{2}BC\sqrt{(4-0)^{2}+(0-0)^{2}  }

         = 12 units^{2}

A stone is thrown upward from ground level. With what minimum speed should the stone be thrown so as to reach a height of 81 fee
butalik [34]
Use the kinematics equation:
v1^2-v0^2=2as
since v1=0 (at height of 81 ft), and a=g=-32.2, substitute values:

0-v0^2=2*(-32.2)(81 ft)
Solve for v0
v0=sqrt(2*32.2*81)=72.2 m/s
