Directions: Using the digits 1 to 9, at most one time each, create an equation where x has the smallest possible value. Experiment with strategies and try different variations of numbers.

The answer to your question is i think 7

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct

The correct answer is 7
