AND PLEASE SHOW YOUR WORK :))

  A: c^2

  B: (1/2)ab

  C: a^2 +b^2 = c^2 . . . Pythagorean theorem

Step-by-step explanation:

A. The area of the square with side length c is the product of the side lengths:

  small square area = c·c = c^2

B. The area of a triangle is half the product of its base and height:

  triangle area = (1/2)ab

C. Doing what the instructions say, we have ...

  a^2 +2ab +b^2 = 4(1/2)ab +c^2

  a^2 +b^2 = c^2 . . . . . . . . . . . . . . . . .  subtract 2ab from both sides

This is a statement of the Pythagorean theorem.

idk wbu

step-by-step explanation:

the degrees would remain the same ( the number to the left of the decimal point.

the multiply the decimal by 60 to get the minutes and use the numbers to the left of the decimal point.

then multiply the decimal portion of that by 60 for the seconds and round off as needed.

39 .956652

the 39 remains the degrees.

the minutes = 0.956652 x 60 = 57.39912

the minutes = 57

the seconds = 0.39912 x 60 = 23.95 = 24 ( rounded to nearest tenth)

so 39.956652 = 39 degrees, 57 minutes and 24 seconds

-75.159809

the -75 remains the degrees

the minutes = 0.159809 x 60 = 9.58854

the minutes = 9

the seconds = 0.58854 x 60 = 35.31, rounded to nearest tenth = 35.3 seconds

so -75.159809 = -75 degrees, 9 minutes and 35.3 seconds.

the first coordinate is north or south, since it it positive it is north.

the second number is east or west, because it is negative it is west.

39 degrees, 57 minutes and 24 seconds n

-75 degrees, 9 minutes and 35.3 seconds w
