Answer: x = 131
Reasoning: Alternate interior angle theorem
The angles shown are inside the parallel lines, so they are interior angles. They are also considered alternate angles because they are on alternating sides of the transversal cut. Alternate interior angles are congruent when we have parallel lines like this.
The answer to the variable r is r=-4
15% of 80 is 12.
To check this, you can multiply 80 x 0.15, which gives you an answer of 12.
Answer
when you place a source of signal at a focal point of an ellipse, the signal will be reflected to the other focal point position
When you place a source of rays as a signal at the focal point of a hyperbola, the ray will be reflected directly away from the other focal point
When you place a source of rays as a signal at one of the parabola focus, the ray will be reflected in lines that are parallel to the axis of the parabola.
