Since the sum of the angles of a triangle is 180 degrees, we simply have to add all the angles and equate it to 180 to solve for x. So:100 + 12x + 4 + 14x - 2 = 18026x = 78x = 3
So, x is equal to 3.
Answer:
the best number is 17 cuz the sequence is to add 2 sooo it's 17 then 19
20 and 24 are the answers
17 25 and 1/2 34. 42 and 1/2
Well, point slope is y - y1 = m(x-x1) So A and D are out. And the negative would cancel each other out for a positive, answer being, B.
