SOMEONE PLEASE HELP ME

14. A

15. A

16.

17. B

18. always

19.sometimes

20. never

Step-by-step explanation:

14. internal angles must equal 360

a+b+36+113=360

a+b=211

the only one that equals 211 is a

we can see that a>b

therefor the answer is a (a=144 and b=67)

15. ((2n-2)+(4n+6))/2 = n+12

(6n+4)/2 = n+12

3n+2=n+12

2n=10

n=5

**I am not completely sure if this is right, I would try to check it if I were you**

16. it is a quadrilateral, so the interior angles must equal 360 again

angle1 + angle2 + 110 + 98 = 360

angle1+angle2= 360-208

angle1+angle2=152

there are only two answers that add up to 152, so we know the answer will be c or d

17. we know that angle1 is equal to 90 because the lines are perpendicular

angle2 is 20° because the perpendicular lines cut the angle in half, which means both at the bottom will be 20

this realization results in you getting b as the answer

18.always

19. sometimes

20. never

maybe i can
