<span>Angle 7 and 5 are vertical angles, so they're equal.
Angles 7 and 8 are supplementary, so they have to add up to 180.
2x + 15 + 3x = 180
Solve for x, then plug it into the expression for angle 7 to get you answer</span>

Step-by-step explanation:
85 = 25 + x3
60 = x3
20 = x
1,368 x 10^9th is 1.368 x 10^12
Because these are consecutive integers and not consecutive even or consecutive odd, we use n + n + 1, which simplifies into 2n + 1, which means that you should use Option D.
Now, we solve:
2n = 106
n = 53
Because 53 + 1 is 54, we know the that the integers are 53 and 54.
