Answer:
65
Step-by-step explanation:
the sum of interior angles in a triangle equal to 180°

For this case we have the following equation:

From here, we must clear the value of x.
Adding By on both sides:

Then, dividing both sides by A we have:

Answer:

x equals the quantity B times and plus C all over A
4 + -6 = -2 the lines go from 0 to 4 so + 4 then back 6 spots to -2 so 4 + -6 = -2
