Answer:
Step-by-step explanation:
Hi
Here if : x = 1, y = 2 yields sides of 11, 10, and 15 units
So, it's not necessarily isosceles. Eliminate choice d). (If you had chosen x = y = 1,
choice d) would be in the running until looking at further information.)
Here is the conclusion:
A) If the sum of the squares of the two shortest sides is greater than the square of the longest side, it is an acute triangle.
B) If the sum of the squares of the two shortest sides equals the square of the longest side, it is a right triangle.
C) If the sum of the squares of the two shortest sides is less than the square of the longest side, it is an OBTUSE TRIANGLE
