Hi! I'm not too familiar with hanger diagrams but I believe the equation you're looking for is 12 = 4c since both sides have to be equal and there are an amount of <em>c</em>'s that make up 12.
Hope this helps! :)
R u serious,
y=1/2x
graph at (0,0), and (10, 5)
clearly
ez.
The correct answer would be c
So for the 40-40-90 degree triangle, whenever the two legs are x values, then the hypotenuse is x value times the square root of 2.
--> a changed into a√2
√2 changed in √2 * √2
= 2
So the hypotenuse of the 40-40-90 degree triangle is 2.
Now for the 30-60-90 degree triangle, the smallest leg with the value of x is then changed to the value of x√3 if finding the longer leg.
-> a is changed to a√3
2 is changed into 2√3
So, y is 2√3 or approximately 3.46 units.
