igor_vitrenko [27]

Answer:

C = 90 - d

Step-by-step explanation:

We know that the sum of complementary angles is 90 degrees

i.e.

Angle 1 + angle 2 = 90°

As it is stated in the question that one angle is d then

d+C = 90

Write the sum of the numbers as the product of their GCF and another sum <br> 56+64
olga2289 [7]
This is a question about finding the GCF or the greatest common factor for these two numbers.  The real question there is what is the largest number that both 56 and 64 can be divided by and still give out integers (meaning, whole regular counting numbers).  This number turns out to be 8.  56/8 = 7.  64/8 = 8.  The GCF gets pulled to the outside of the parenthesis and the divided numbers remain on the inside being added together.  It looks like this, 8(7+8).
