Answer:
x = 4
Step-by-step explanation:
Sum of angles (in degrees) in a triangle = 180
so
60 + 70 + 12x + 2 = 180
Add like terms
132 + 12x = 180
subtract 132 from both sides
12x = 48
divide both sides by 12
x = 4
Because of the order of operation, you would first do the division, which makes the expression 8-6+3. Now you would perform them left to right, first into 2+3, then get your answer of 5.
The answer would be 18/96. Hope this helps and it was ez.
