Answer:B is the answer
Step-by-step explanation:
A regular polygon is a closed figure
All its angles are equal in measure.
and all its sides are congruent
Answer:
Angle 1: 115
Angle 2: 65
Angle 3: 115
Angle 4: 65
Angle 5: 115
Angle 6: 65
Angle 7: 115
Step-by-step explanation:
Find the value of angle 2 by applying the vertical angles theorem (65)
Find the value of angle 1 by applying the supplementary angles theorem from the original angle (180 - 65 = 115)
Find the value of angle 3 by applying the vertical angles theorem from angle 1 (115)
Angles 4, 5, 6, and 7 are on a line parallel to the orginal line, cut by the same transversal, so they have the same values, according to the same side interior/exterior angles theorems.
Answer: 75º
Step-by-step explanation:

Answer: f (-2) = 21
Step-by-step explanation:
For f (-2), substitute the value of x into the equation:
F(-2) =3(-2)^2 - 2(-2) + 5
=3 (4) + 4 + 5
= 12 + 4 + 5
f (-2) = 21
