The angle measures of a triangle are shown in the diagram 5X degrees, 74°, 4X plus 7°. What is the value of x

1 answer

To find the value of x, we can use the fact that the sum of the angles in a triangle is always 180 degrees.

So, we have the equation:

5x + 74 + 4x + 7 = 180

Combining like terms, we get:

9x + 81 = 180

Subtracting 81 from both sides, we have:

9x = 99

Dividing both sides by 9, we find:

x = 11

Therefore, the value of x is 11.
