what is the value of x?

!

x = 21

Step-by-step explanation:

Sum of interior angles in a triangle = 180

so

3x + x -4 + 100 = 180

4x + 96 = 180

4x = 84

x = 21

x = 21

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180

3x + 100 + x - 4 = 180 ← simplify the left side

4x + 96 = 180 ( subtract 96 from both sides )

4x = 84 ( divide both sides by 4 )

x = 21
