S = n(a1 + an)/2
2S = n(a1 + an)
2S = na1 + nan
nan = 2S - na1
an = (2S - n a1)/n
F(n)=235-(235*.3^n)+50n is your equation where * is multiplication and ^ it to the power to.
Answer:
1 75/100 or 3/4
Step-by-step explanation:
if you simplify 1 75/100 its 3/4
The correct answer is 0,10
Side BC is congruent to side BC.
Using the congruent angles and the angle bisectors, you can get two angles congruent to two other angles, so you use ASA to prove the triangles congruent. Then you use CPCTC to prove the sides congruent.
Answer: C.) ASA
