3(a + b) the answer to the question
Answer:
Two angles are Adjacent when they have a common side and a common vertex (corner point) and don't overlap. Because: they have a common side (line CB)
Step-by-step explanation:
We can sum two fractions if they have the same denominator, so we have to rewrite both fractions so that they'll have the same denominator.
We can generate equivalent fractions by multiplying both numerator and denominator by the same number.
So, we have

Similarly, we have

Now we can sum the fractions:

The answer should be C.

The area of the parallelogram = base x height ......(1)
Take the base as 280 ft. Draw an altitude on the base which is your height. In the triangle formed your third side
is the one with 250ft, your hypotenuse. You can find the height by using Pythagoras Theorem,
(250)*2 = (h)*2 + (280)*
solve for 'h' and substitute in (1) and voila you have the area of the parallelogram.
