Answer:
65
Step-by-step explanation:
Since these 115 and the angle adjacent to x are alternate interior angles, then that angle is equal to 115. That angle and x add up to 180, so we do 180-115, which is equal to 65.

Answer:
Exact length = 2*sqrt(137) cm
Approximate length = 23.409 cm
====================================================
Work Shown:
Use the Pythagorean theorem
a^2 + b^2 = c^2
8^2 + 22^2 = c^2
64 + 484 = c^2
548 = c^2
c^2 = 548
c = sqrt(548)
c = sqrt(4*137)
c = sqrt(4)*sqrt(137) ..... use the rule sqrt(x*y) = sqrt(x)*sqrt(y)
c = 2*sqrt(137) .... this is the exact length
c = 23.4093998214392 ... use your calculator to find the approximate length
c = 23.409
I rounded to three decimal places, but feel free to round however you want. Or be sure to follow any rounding instructions your teacher provides.
5 * 10^9 * 2.3 * 10^7
= 5 * 2.3 * 10^9 * 10^7
= 11.5 * 10^16
= 1.15 * 10 * 10*16
= 1.15 * 10^17
