<span>a = (90-a)/2 - 18
this means that the angle equals half its complement minus 18 degrees.
this means the same as the angle equals 18 degrees less than half its complement.
solve for a.
equation is:
a = (90-a)/2 - 18
simplify by removing parentheses to get:
a = 90/2 - a/2 - 18
simplify further to get:
a = 45 - a/2 - 18
combine like terms to get:
a = 27 - a/2
add a/2 to both sides to get:
a + a/2 = 27
multiply both sides of the equation by 2 to get:
2a + a = 54
combine like terms to get
3a = 54
divide both sides of the equation by 3 to get:
a = 18
your answer should be that the angle is equal to 18 degrees.
if the angle is 18 degrees, then its complement is equal to 90 - 18 = 72 degrees.
half its complement is equal to half of 72 is equal to 36 degrees
18 degrees less than that is equal to 36 - 18 is equal to 18 degrees.
Your answer is that the measure of the angle is 18 degrees.</span>

Answer:
The correct answer is:
we cannot take an even root of a negative number in the real number system.
Explanation:
A rational exponent is another way of writing a root. The denominator of the rational exponent will be the root, and the numerator will be the power of the number under the root. If the denominator is even, this means we are taking an even root, such as square root, 4th root, etc.
If the base is negative, this means we want an even root of a negative number.
Any even root can be broken down into a series of square roots, done one after another.
However, we cannot take the square root of a negative number using real numbers; this is because a square root is a number multiplied by itself to get the answer; a negative times a negative is a positive, as is a positive times a positive, so there is no way to multiply the same number twice and get a negative.

Answer:
80 Strawberries
Step-by-step explanation:
If she picked 120 strawberries in 6 hours
Then in 1hour she picked 120/6 = 20 strawberries
