Answer:
I think x = 123.5°
Step-by-step explanation: Why?
Because since it didn't say what one of the angles of the triangles were. I think they were just expecting you to assume that both of the missing angles of the triangle are the same. So, since the sum of a triangle equals 180°, you would do 180°- 67°, which equals, 113°. Then since you are trying to find what x° equals... You would do 113° ÷ 2, to find the two missing angles of the triangle, which equals 56.5°. So, now you know that each angle of the triangle equals 56.5°. And before I go on, just incase you don't know, a straight angle is 180°. So, since x° is on a straight angle... you would do 180°- 56.5°, which equals, the angle x°. So, x° equals 123.5°. Now, 123.5° might not be the right answer, only because in the problem it includes 61°... and I don't know why or what to do with that. So, hopefully 123.5° is the correct answer. I would try 123.5°, if not than I am sorry. But it does seem reasonable, since x° has to be more than 90°, but also less than 180°.
