We have given
hypotenuse=<span>6√2
let us suppose leg =a
using Pythagorean theorem
a^2+a^2=(</span><span>6√2)^2
</span>2a^2=36*2
diving by 2 on both sides
a^2=36
taking square root on both sides
√a^2 =<span>√36
a=6
therefore
</span><span>the leg of each isosceles right triangle is 6</span>
8am : -14F
noon : -14+10 = -4F
increase between noon and 4 is 2*10 =20
4 pm: -4F + 20 = 16F
temperature at 4 pm is 16F
PQS = 40 because if you look at the image above it half equals 20 and 20+20=40
