It is convenient to remember that 5-12-13 is a Pythagorean triple.
Her ladder is 12 ft above the ground where it rests on the house.
_____
Using the Pythagorean theorem, you are given the hypotenuse as 13 ft and one leg as 5 ft. Then the other leg is
.. √(13^2 -5^2) = √(169 -25) = √144 = 12
The answer is 10, this is because 7 1/2 = 7.5 3/4=.75 and if there is 7.5 inches of ribbon, but cut into .75 pieces you would divide 7.5 by .75 which equals 10.
Answer: Negative 1 The slope of parallel lines is the same.
The attachment shows two such lines, given coordinates labeled.
Step-by-step explanation:
Find the slope of the line passing through the given points.
rise/run
Rise is the difference in y-values 7-(-5) = 12
Run is the difference between x-values -5 - 7 = - 12
The Slope is 12/-12 simplify:
slope = -1
Answer:
90
Step-by-step explanation:
make sure to use BIDMAS
start of by working out everything in the brakets first.
the first bracket would be 50
the second bracket would be -40
the minus these as there is a minus between the brackets
50--40=90
