the amount of decrease divided by the original amount times 100 equals <u><em>percent of decrease</em></u>
Answer:
60 degrees
Step-by-step explanation:
First we need to know how many degrees are in a parallelogram. We can use the formula 180(n-2) (n is the number of sides)
This works out to 180(4-2)=360 degrees.
Now we can set up the following equation as:
2(120)+2x=360 Subtract 240 from both sides to get:
2x=120 Divide by 2 to get:
x=60 degrees
Therefore we know 2 angles are each 120 degrees and the other 2 are 60 degrees.
Makes sense?
Answer
Explanation
The quadratic equation to be solved is
x² + 4x - 4 = 0
The graph of this equation is plotted and attached under 'Answer'.
From the graph, we can see that the solutions of the equation include
x = -4.828 and x = 0.828
The equation has two roots, that is two solutions.
Hope this Helps!!!
