Answer:
the answer to this equation is 2
20 + 2*(3-5)^2 + (30/10)*3
20 + (2*[-2])^2 + (3*3)
20 + (-4)^2 + 9
29 + 16
45
Note that * is used to signify multiplication.
Let
x----> the length side of the hypotenuse
y----> the length side of the <span>unknown leg
we know that
x=2*y----> equation 1
applying the Pythagoras Theorem
x</span>²=y²+3²-----> equation 2
substitute equation 1 in equation 2
[2*y]²=y²+3²----> 4*y²-y²=9-----> 3*y²=9----> y²=3
y=√3 ft
x=2*y----> x=2*√3 ft
the answer is
<span>the lengths of the three sides are
</span>hypotenuse=2√3 ft
one leg=√3 ft
other leg=3 ft
