The center of the circumscribed circle of the triangle
Basically evaluate the riennam sum for infinitely small rectangles
basically we got
in interval form
Use the distributive property
(4x + 2)3
Distribute.
3 * 4x = 12x
3 * 2 = 6
<u>Answer</u>
12x + 6
Well we know the sum of all the angles on a triangle is 180.
And we already know 2 of the sides: 102 and 31. So add them up and subtract it from 180.
102 + 31 = 133.
180 - 133 = 47.
So "x" is 47.
