Answer:
tangent (angle) or tan (angle)
Step-by-step explanation:
tangent (angle) = the leg opposite the angle / the leg adjacent to the angle
The typical tip would be 19.5, you get this from solving or searching up 15% of 130 equaling to 19.5
Angle 8 because supplementary is two angles whose sum is 180°.
60, 60 and 60 degrees
There are two criteria: the angles have to all be equal and they have to add up to 180 degrees. This answer satisfies both criteria.
