The corner of a room where two walls meet the floor should be a right triangle. Jeff makes a mark along each wall. One mark is 15 inches from the corner. The other is 8 inches from the corner. How can Jeff use the Pythagorean Theorem to see if the walls form a right angle?
If the distance across the floor from one mark to the other is
nothing inch(es), then the
Pythagorean Theorem
says that because 15 squared plus 8 squared equals nothing squared
, a right triangle is formed.

The answer is 17, converse of the pythagorean theorem

Step-by-step explanation:

The converse of the Pythagorean Theorem is that a triangle with side lengths a, b, and c for which  is a right triangle.

answer: 32.68

step-by-step explanation:

x=2

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
