Answer:
No, it is not a square
Step-by-step explanation:
If one wall is 19", that would mean the wall perpendicular to this wall is also 19" (in fact all of the walls would be 19"!) If this was a square, then the diagonal we draw at 20.62" would serve as the hypotenuse of a right triangle. One wall would serve as a leg, and another wall as another leg. If this is a square, then the Pythagorean's Theorem would be satisfied when we plug in the 2 wall measures for a and b, and the diagonal for c:
We need to see if this is a true statement. If the left side equals the right side, then the 2 legs of the right triangle are the same length, and the room, then is a square.
361 + 361 = 425.1844
Is this true? Does 722 = 425.1844? Definitely not. That means that the room is not a square.
Answer: second option.
Step-by-step explanation:
You must apply
Then, given the right triangle and the angle D, the opposite side and the hypotenuse of the triangle are the following:
Therefore, when you substitute values, you have:
Reduce the fraction, then you obtain:
Answer:
Step-by-step explanation:
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
step 1
Find the slope of the given line
we have
isolate the variable y
the slope of the given line is
step 2
Find the slope of the perpendicular line to the given line
---> slope of the given line
therefore
The value of m is
