Hey there!
In an isosceles triangle the 2 base angles are congruent, therefore angle B would measure 50 degrees just like the measure of angle A.

Answer: First Option : Sₙ= n/2(a₁ + aₙ)
Step-by-step explanation:
The nth partial sum of an arithmetic sequence or the sum of the first n terms of the arithmetic series can be defined as the sum of a finite number of term in an arithmetic sequence.
It is calculated using the formula:
Sₙ= n/2(a₁ + aₙ)
Where :
a₁ = First term
aₙ = last term
n = number of terms
take 23 2/3 and subtract 6 to get 53/3 or 17 2/3 or 17.667
then you take 17.667 and divide by 11 to get 1.606
