The lengths of the sides of a 30-60-90 triangle are in the ratio 1:2:√3.
The lengths of the sides of a 45-45-90 triangle are in the ratio 1 : 1 : √2
We can get the length of the longest side of the bottom triangle is 9×2÷√3 = $\frac{18}{√3}$
And based on the theory shown on the 2nd step, we can get x (the length of the longest side of the upper triangle) is $\frac{18}{√3}$ x√2

If 23 is subtracted from 8 times the number, the result is the square of 2 less than the number.

pychu [463]

I believe the answer is 116.

23-8=15
8*15=120
sqrt2=4
the number 120-4=116

that’s what i got not sure if that is correct
