Two straight lines of a wire are placed on the ground forming vertical angles. if the measure of one of the angles formed is 72°, what are the measures of the other three angles. explain your answer.

Vertical angles are congruent and if the measure of 1 of the angles is 72 degrees and straight lines equal 180 degrees you have to subtract 72 from 180 which equals 108. So the measures of the other three angles are 108, 108 and 72.
Next time no all CAPS, no yelling!

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
