Question

Find the value of x.

Answer 1

Answer:

In algebra, it is easy to find the third value when two values are given. Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side.    

Step-by-step explanation:

Answer 2

Answer: 59 degrees
Explanation: x + (x + 12) + (x - 9) = 180 (this is because of the angle sum property where the sum of all angles of a triangle is 180 degrees)
x + x + x + 12 - 9 = 180
3x + 3 = 180
3x = 180 - 3
3x = 177
x = 177/3
x = 59
