For two adjacent angles with measures x° and (x+30)° that make up a 90° angle, what is x?

Answer 1

Since the two adjacent angles make up a 90° angle, we can write the equation:

x + (x+30) = 90

Simplifying the equation, we have:

2x + 30 = 90

Subtracting 30 from both sides:

2x = 60

Dividing both sides by 2:

x = 30

So, x is equal to 30°.
