To find the value of x, we know that the sum of the angles in a triangle is 180 degrees.
We have the equation:
5x + 74 + (4x + 7) = 180
Combining like terms, we get:
9x + 81 = 180
Subtracting 81 from both sides, we get:
9x = 99
Dividing both sides by 9, we get:
x = 11
Therefore, the value of x is 11.
