<em><u>The solution to the inequality is:</u></em>

<em><u>Solution:</u></em>
Given inequality is:

We have to find the solution to given inequality




Simplify the above inequality


Remember that, change the inequality sign if you divide or multiply both sides by a negative number
If you divide or multiply both sides by a positive number,the inequality sign will not change



Thus the solution to inequality is found
The sum of a straight angle is 180°
So 77+x=180
Subtract 77 from both sides and the equation is
x=77
The measure of the other angle is 77°
The solution of <span>0 = x2 − 5x − 36 is x = - 4 and x = 9
