Answer:
1 and 3 are 47 degrees and 2 is 133 degrees
Answer: Neither odd nor even
Step-by-step explanation:
For it to be odd, f(x)=-f(-x).
For it to be even, f(x)=f(-x)
Hence, it is neither odd nor even.
Answer:
y = 26
Step-by-step explanation:
The angles of a linear pair total 180°.
__
(2y +1)° +(5y -3)° = 180° . . . . the sum of the angles is 180°
7y -2 = 180 . . . . . . divide by °, collect terms
7y = 182 . . . . . . . . add 2
y = 26 . . . . . . . . . divide by 7
_____
<em>Additional comment</em>
The angle measures are (2(26) +1)° = 53°, and (5(26) -3)° = 127°. These total 180°, as they should.
