Hi!
y = 16
x = 32
<h3 /><h3>
In 30-60-90 triangles, the hypotenuse is double the length of the shortest leg, and the longer leg is
times the shorter leg.</h3>
We are given the longest leg. To find the shortest leg, we must divide the longest leg value by 

The radicals cancel out and we are left with 16.
The length of y (the shortest leg) is 16.
Now, we also know that the hypotenuse is double the shortest leg. The shortest leg is 16, so if we double that, it's 32.
First term = 2(1) - 3 = 2 - 3 = -1
Answer:
Selena is correct because she simplified correctly and then evaluated correctly after substituting the values for the variables.
I did this lesson i asked my teacher to help me but i did this problem on my own so i hope its right :)
