# Angles A and B are complementary. If measurement of angle #A = 3x-8# and measurement of angle #B = 5x+10#, what is #x#?

To find the value of (x), set up the equation:

[3x - 8 + 5x + 10 = 90]

Solve for (x).

Since angles A and B are complementary, their measures sum up to 90 degrees.

Given: Measurement of angle A = 3x - 8 Measurement of angle B = 5x + 10

According to the definition of complementary angles:

Angle A + Angle B = 90 degrees

Substitute the measures of angles A and B:

(3x - 8) + (5x + 10) = 90

Combine like terms:

3x + 5x - 8 + 10 = 90 8x + 2 = 90

Subtract 2 from both sides:

8x = 88

Divide both sides by 8:

x = 11

Therefore, x equals 11.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
