Write an inequality to describe the possible values of x.
Help please thank you?
Easy, just use the Pythagorean theorem. It states that for a right triangle, two legs both squared and summed equals the hypotenuse squared. A wider angle makes way to a longer hypotenuse, so our theorem is adjusted:
We then have...
BTW, I don't understand from the drawing how two sides are equal (5x)? Nevertheless, I will continue with the algebra.
note, that there was a and was divided into and .. so, 30 + 95 = 125 subtracted from 180 gives 55.. thus, , which implies or
for the lower bound, we have x cannot be non-positive, otherwise, we would have a negative o zero length given by 5x.. thus, we can assume that
