They gave you (blue) find the measurement of (yellow) since (blue)+(yellow) make up a line they =180
105+(yellow)=180
-105 both sides
yellow= 75
105+(yellow)=180
-105 both sides
yellow= 75
The value of x is equal to -5/6
To solve this question, we have to add two polynomials together. The polynomials are;
This involves adding of two or more different polynomials together. The polynomials adding together are or must be of the same degree. i.e x^2 must add to another coefficient of x^2 and x^3 adds to another coefficient of x^3 and so on.
In this given question, let's add the polynomials together.
Now, let's equate this with the last polynomial given
Let's solve for x

N.b., this is copied from an answer I wrote for someone else.
Thinking about the graph of y, the rate of change is zero whenever there is an extremum.
First, differentiate y.
Next, find the zeros of y' by factoring.
Now, we substitute these x-values into the original equation to find the coordinates.
