What are the measures of Angles a, b, and c? Show your work and explain your answers.
Lyrx [107]

Answer:

  (a, b, c) = (30°, 60°, 105°)

Step-by-step explanation:

Angle "a" and 30° are vertical angles, hence equal.

Angle "b" and angle "a" are complementary angles, so b = 90° -30° = 60°.

Angle "c" is supplementary to the one marked 75°, so is 180° -75° = 105°.

___

Angles "a" and "b" are complementary because the sum of angles in a triangle is 180° and the third angle in that triangle is 90°. Then ...

  a+b = 180°-90° = 90°

___

75° and "c" are supplementary, because they are linear angles. The angle measure of a line is 180°, so that is their total measure.

Which set of ordered pairs represents a function?
Lemur [1.5K]
It would be D, because to be a function, a set of ordered pairs cannot have the same x value. The y value can be the same though.
(5,6), (8,6), (9,6) 
As you can see, all of the x values are different, so it is a function.
