Answer:

Step-by-step explanation:
The upside down exclamation point(¡) denotes the subfactorial in math. There are two ways to approach solving the subfactorial, one being exact, while the other is a more practical approach.
One way (the mathematically correct way) is using the formula:
n=n!∑[(-1)^k]/k!, where k starts at 0 and counts to n.
However, another, less accurate way is simply ¡n = [n!/e], where the brackets mean to round to the nearest integer, which returns 2.25268983 * 10^(103)
Hope it helps :) and let me know if you want me to elaborate, or if the notation used was intended to be something else, as the subfactorial of 72 seems like an unnecessary amount of tedium.

Answer:
x = 20
Step-by-step explanation:
The sum of the opposite interior angles of a triangle is equal to the exterior angle
x + 2x+10 = 70
Combine like terms
3x+10 = 70
Subtract 10 from each side
3x+10-10 = 70-10
3x = 60
Divide each side by 3
3x/3 = 60/3
x = 20
