<span> It would depend on the number of rows?
This is an arithmetic sequence and the sum of n terms is -->
n/2(2a+(n-1)d), where a is the first term and d is the common
difference. In this case a = 10, d =6
n/2(20+6(n-1)) = 3n^2 + 7n = ANSWER
n = number of rows

Answer:
Total money = $30,00,000
Step-by-step explanation:
Given:
4/5 money spend on house
3/4 remaining money spend on luxury yacht
2/3 remaining money spend on trip to space
Remaining $50,000 to charity
Find:
Total money
Computation:
Assume Total money = x
So,
Spend on house = [4x/5]
Spend on luxury yacht = [x-4x/5]3/4 = 3x/20
Spend on trip to space = [x/5-3x/20]2/3 = x/30
Remaining money = x/20 - x/30 = x/60 = $50,000
So,
x/60 = $50,000
x = $300,000
Total money = $30,00,000
In an isosceles triangles the sides that are congruent form two congruent angles...you should be given one of those angle measures or the other one...if you are given one of the angle measure formed by the congruent side you know the one opposite it is the same and you know all the measures of angles in a triangle = 180 so you should be able to find them all
