If two adjacent angles with measure (x+18) and x are inside a 90 degrees angle, what is the equation for the two adjacent angles?

Answer 1

The sum of the measures of the two adjacent angles is equal to 90 degrees. Therefore, the equation for the two adjacent angles is:

(x + 18) + x = 90

Simplifying:

2x + 18 = 90

Subtracting 18 from both sides:

2x = 72

Dividing both sides by 2:

x = 36

So the two adjacent angles have measures of 36 + 18 = 54 degrees and 36 degrees.
