Consider the finite arithmetic sequence,
Use the explicit formula for an arithmetic sequence,
...... (83.84.94.92.91.100
First term of the sequence is
A) Ang 1 + Ang 2 = 90
B) Ang 1 = Ang 2 + 20
B) Ang 1 -Ang 2 = 20 then adding this to equation A produces
2 Ang1= 110
Ang 1 = 55 degrees
Ang 2 =35 degrees
Answer:
divide 10 by three, you should get 3.33
