Step-by-step explanation:
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 : √2We can get the length of the longest side of the bottom triangle is 9×2÷√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
x√2 Â
