An angle measures 68° more than the measure of a complementary angle. What is the measure of each angle?
kifflom [539]

Answer:

11° and 79°

Step-by-step explanation:

Complementary angles sum to 90°

let x be one angle then the other angle = x + 68 , hence

x + x + 68 = 90

2x + 68 = 90 ( subtract 68 from both sides )

2x = 22 ( divide both sides by 2 )

x = 11

The 2 angles are x = 11° and x + 68 = 11 + 68 = 79°

As a check : 11 + 79 = 90

What is 4 over the quantity of 3 to the negative 2nd power?
katrin2010 [14]
If I've understood your question, you're asking about this:

\frac{4}{3^{-2}}

A number raised to a negative power is the same as the inverse of that number raised to the positive power. Basically the number moves from the numerator to the denominator or the denominator to the numerator. So 1/(3^-2) is the same as 1 / (1/3^2), which is the same as 3^2. That means what you have here is 4 x 3^2, which is 36.
