Answer: The answer would be f^-1 (x) = x/2 - 3/2
Answer:
c=6
Step-by-step explanation:
c+7=13
-7 -7
c=13-7
c=6
The measure of a triangle is 180 degrees. In other words the sum of the angles of a triangle is 180 degrees
To solve for x set all of the expressions of angles equal to 180 and isolate x
11x - 3 + 7x + 5 + 13x - 8 = 180
31x + (- 6 + 6) = 180 + 6
31x/31 = 186 / 31
x = 6
To find the measure of each angle plug 6 into the x into each individual expression
