To find the value of x, we need to set up an equation using the fact that the sum of angle measures in a triangle is 180 degrees.
The given expression represents three angles: 5x, 74, and 4x+7.
So, we can write the equation as follows:
5x + 74 + 4x + 7 = 180
Combining like terms:
9x + 81 = 180
Subtracting 81 from both sides:
9x = 99
Dividing both sides by 9:
x = 11
Therefore, the value of x is 11.
