Answer:
Step-by-step explanation:
Left side
4x + 2x - 10
6x - 10
Right side
6x - 12
Eventually when you equate these sides, you will get an absurd answer because the 6x term will be subtracted out on both sides
that means you get -10 = - 12
which destroys the whole concept of equality. There is no solution.
Since we know that a triangle equals to 180 degrees, we should start by adding together the two known angles inside the triangle. To determine to measure of the unknown angle, be sure to use the total sum of 180 degrees. If two angles are given, add them together and then subtract from 180 degrees. If two angles are the same and unknown, subtract the known angle from 180 degrees and then divide by 2.
I have tried this and I think it is c
To find the mid segment, it is half of the sum of the bases
for number 13 it's 7+13=20 20/2=10
number 14 it's 12+9=21 21/2=10.5
number 15 it's 22+18=40 40/2=20
Answer:
28th
Step-by-step explanation:
Put that value into the formula and solve for n.
191 = 2 +7(n -1)
(191 -2)/7 = n-1 . . . . . . . subtract 2 and divide by 7
27 +1 = n . . . . . . . . . . . .add 1
191 is the 28th term in the sequence.
