Answer:
32
Step-by-step explanation:
12 * (3 + 2²) / 2 - 10
12(3 + 4) / 2 - 10
12(7) / 2 - 10
84 / 2 - 10
42 - 10
32
Best of Luck!
Here's a pattern to consider:
1+100=101
2+99=101
3+98=101
4+97=101
5+96=101
.....
This question relates to the discovery of Gauss, a mathematician. He found out that if you split 100 from 1-50 and 51-100, you could add them from each end to get a sum of 101. As there are 50 sets of addition, then the total is 50×101=5050
So, the sum of the first 100 positive integers is 5050.
Quick note
We can use a formula to find out the sum of an arithmetic series:

Where s is the sum of the series and n is the number of terms in the series. It works for the above problem.
The anwer for that would be a; angle 1 would be congurent to angle 4.
Answer:
the value of x = 10°
Step-by-step explanation:
here's the solution :-
we know that, the measure of exterior angle of the triangle is equal to the sum of opposite two interior angles.
so,
=》5x - 7 + 6x + 14 = 14x - 23
=》11x + 7 = 14x - 23
=》7 + 23 = 14x - 11x
=》3x = 30
=》x = 30 ÷ 3
=》x = 10°
The quotient between 41/3 is 13 to 14. Easy Division.
