This conjecture is false, A and C don't have to be complementary angles.

Let Angle A be 100 and Angle B be 80 degrees. They are supplementary (sum of 180).
Let Angle C be 100 and Angle B is still 80 degrees. They are supplementary.

However, Angle A and Angle C are not complementary (sum of 90).

Use inverse operations to solve equation 15=x/6-1​
beks73 [17]

Answer:

x=90.

Step by step explanation:

To solve the expression 15=\frac{x}{6}-1, and obtaining a value for x we can do the following:

  1. Add 1 both sides of the equation. This will result in 15+1=\frac{x}{6}-1+1⇒16=\frac{x}{6}.
  2. Multiply both sides by 6, which yields 15\times6=\frac{x}{6}\times6. This results in 90=x.
