Question 1: The shorter leg is 30 degrees so, 3 times the length of the shorter leg put into a quick equation is 30 x 3. So what is 30 x 3?

30 x 3 = 90. So that is why question 1 is 3 times the length of the shorter leg

for 45-45-90 triangle,
since 2 angles are equal, the two legs will be equal.|dw:1359742414724:dw|

in other words, both legs are the same length (since it is an isosceles triangle) and the hypotenuse has length \(\sqrt{2}s\) is \(s\) is the length of the side
