Classify TRIANGLE ABC by its angles if m<A=X, m<B=2X,AND m<C=3X obtuse isosceles right equilateral 39. In a plane, line b is parallel to line f, line f is parallel to line g, and line h is perpendicular to line b. Which of the following cannot be true? g || h b || g the "T" should be upside down b T h h T f 40. mc016-1.jpg If m<13=m<15=m<7,what conclusions can you make about lines a, b, c, and d? Only lines c and d are parallel. No conclusions can be made. Lines a and b are parallel, and lines c and d are parallel. Only lines a and b are parallel.

For the first one you need to find the angles. One angle is x, one is 2x and the third one is 3x. Add those all together and you get 180. Write and solve the equation. When you know x, you can find the three angles and then you can classify the triangle.
