Arada [10]

Answer:

m = 40

Step-by-step explanation:

The triangle inside the circle has 2 equal sides ( the radii ) of the circle, thus

The base angles are congruent both 50°

The 3 angles on the tangent sum to 180°, so

m + 50 + 90 = 180

m + 140 = 180 ( subtract 140 from both sides )

m = 40

I need it by tmr<br> ill give brainliest thx
Zina [86]

Answer:

21. B. Graph Z

23. A. neither function nor relation

24. D. relation only

Step-by-step explanation:

21. Graph Z is the only graph which does not pass the vertical line test

23. The graph does not pass the vertical line test, AND it is not merely given x and y points like a relation. It is graphed as a squiggly line with no given x and y points, therefore you could not make a relation from it either.

24. There is an x value of -4 twice, meaning the set does not pass the vertical line test, HOWEVER, it is a given collection of x and y values, making it a relation.

I would appreciate brainliest, have an amazing day
