When two lines are parallel, the acute angles they form with a transversal are to the obtuse angle?

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles

What is the frequency of the sinusoidal graph?

Need match the functions with correct transformation. f(x) = -3x f(x) = |x-1|+3 f(x) = √(x+3) 1/2x² f(x) = (x+1)²-3 4|x| 1. compress by a factor of 1/2 2. stretch by a factor of 4 3. shift to the left 3 4. shift to the left 1 5. shift up 3 6. reflection
