Find the value of n 2n and 3n are complementary angles?

Complementary angles add up to 90 degrees.

Therefore, we have:

n + 2n = 90
3n = 90
n = 30

So, the value of n is 30.

Complementary angles add up to 90 degrees. So we can write:

2n + 3n = 90

Combining the like terms:

5n = 90

Now dividing both sides by 5, we get:

n = 18

Therefore, the value of n is 18.
