Answer:
An angle measuring 100 degrees would be supplementary to any angle measuring 80 degrees, but it cannot be called supplementary by itself. "Complementary" and "supplementary" are terms that describe the relationship between two angles. They are comparative words like "larger."

Answer:
10.) is 6
11.) is also 6
Step-by-step explanation:
10.) is 6
because when you subtract exponents 6-3 you get 3 as the exponent which is equal to the first one
11.) is also 6 because subtract the exponents and you get 4.
also is number 12 r^4 I cannot see it . But I will solve for it as 4.
12.) is 3 . because 4 times 3 is 12.
Answer: AE = 120.83 m DE= 148.66 m
The perimeter of the pentagon is 699.49
Sketch attached.
Step-by-step explanation: First we have to imagine the shape of the pentagon. In order to satisfy the requirement "that E is 50 m from the side AB and 30 m from the side BC," <em><u>this must be a concave pentagon. </u></em>
To determine the lengths of sides AE and DE, subtract the given distances of E from the lines, and use those values in the Pythagorean Theorem.
AE:

DE:

Add those lengths and the remaining sides of the "rectangle shown below" to calculate the perimeter.
280+150+120.83+148.66= 699.49
