Whats the question so I can answer
Comment
The way to handle this is to realize that the 180 degree angle (the two supplementary angles added together to make 180o by definition) is actually divided into 6 parts. There are 2 parts for the smaller angle and 4 for the larger.
Added together the 2 angles = 180
Equation
Let one of the 6 parts = x
2x + 4 x = 180
Solve
2x + 4x = 180 Add the like terms on the left together.
6x = 180 Divide by 6
x = 180/6
x = 30
Answer
Since one angle is 2 parts (the smaller angle)
2 * 30 = 60
And the larger angle is
4 * 30 = 120
The two angles are
60,120 <<<< answer.
Further comment.
The two angles are supplementary 60 + 120 = 180
One angle is twice as big as the other. 2*60 = 120
if a < 0, then the parabola opens down . The vertex is the lowest or highest point (depending on direction) on the graph of a quadratic function. Basically you will find the x value of the vertex first and then just plug that value into the function to get the y or functional value of the vertex. :)
