There are several ways to find the zeros of a quadratic function. One of my favorite is to use a graphing calculator to graph it. The zeros can be read directly from the graph.
The zeros are -5 and 6.
The sum of interior angles of a pentagon is given by:
(n-2)*180
where
n=number of sides
thus the sum of angles in a pentagon will be:
(5-2)*180
=540
hence to evaluate the missing angles we shall proceed as follows:
sum of the given angles is:
63+119+125+116
=423
thus the missing angle, x, will be:
x+423=540
x=540-423
x=117°
9 + x = 17
17 - 9 = x
x = 8
0.25 because there is 4 colours and obviously red is 0.75 percent and green and blue can’t be lower than 0.5 cuz that’s for yellow and there’s no 0%
(That makes no sense but it’s 0.25%)
