To find the length of AB, substitute the value of AB into the equation and solve for x. The length of AB is 51.
In the question, we are given that Side AB = 3x + 9 and Side BC = 5x - 19.
We need to find the length of AB.
To do this, we substitute the value of AB into the equation and solve for x.
3x + 9 = AB
Now, we can substitute the value of AB into the equation and solve for x:
3x + 9 = 5x - 19
9 + 19 = 5x - 3x
28 = 2x
x = 14
Now, we substitute the value of x back into the equation for AB:
AB = 3(14) + 9 = 42 + 9 = 51
Therefore, the length of AB is 51.
The probable question may be:
Side AB=3x + 9 , Side BC=5x-19
What is the length of AB?
A. 14
B.51
C. 28
