Answer: D. a1=15.75,an = an -1 -1.5
Step-by-step explanation:
Sorry about the no explanation, but the answer is correct.
(Bc)/(ab)=tan1
(Ef)/(ec)=tan2
Angle 1= angle 2
Tan1=tan2
(Bc)/(ab)=(ef)/(ec)
...
24x-1+20x+5=180
44x+4=180
44x=176
x=4
Therefore, 20x+ 5 is equivalent to 20(4)+5
20(4)+5
80+5
85
Hope this helps :)
