Answer:
x = 47
Explanation:
1. Understanding
a. Know that a straight line is 180 degrees total
2. Subtract
a. Knowing that a straight line is 180 degrees in total, you have to subtract
b. Subtract 180 - 86, where 180 is the angle of the straight line and 86 is the given variable.
180-86= 94
3. Divide
a. It says to find 2x, and you have to do opposite operations to find x
b. You have to divide 97/2 to get 2x, because when you get the number, then you have to find 2x of that number, and then you have to multiply.
c. 97/2 = 47 Degrees
4. Check
a. 2x = 2(47)
b. (47)2 = 47 x 2 = 94
c. 94 + 86 (Given variable) = 180
And a straight line is 180 degrees meaning that this is correct
x = 47
Hope this helps :)
