Answer:
70 = 1/2 b *8
17.5 inches =b
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh
We know the area and the height
70 = 1/2 b *8
70 = 4b
Divide each side by 4
70/4 = 4b/4
17.5 =b
sum = x(n+1)/2
where x is the number of the term ( in this case 52)
n is the last number in the series( which is not given in the problem)
The answer is D.
Hope this helps :)
