In euclidean geometry, the sum of the measures of the interior angles of a pentagon is 540°. predict how the sum of the measures of the interior angles of a pentagon would be different in spherical geometry. a. the sum would be greater than 540. b. the sum would still be 540°. c. the sum would be less than 540°. d. the sum would less than or greater than, but never equal to, 540°.

2-3 6. use your equation to find how high tyler will have to climb to scale the peak. (4 points: 2 points for correctly substituting values, 2 points for the correct height)

What is the average diastolic blood pressure for adults

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
