Answer:
NO
Step-by-step explanation:
Longest side of the triangle has the length = 90 feet
Other two sides are 45 feet and 76 feet
If the triangle is a right triangle then square of the longest side is equal to the sum of squares of the other two sides.
=> [tex]\[90^{2} = 45^{2} + 76^{2}\][/tex]
Left Hand Side = [tex]\[90^{2}\][/tex] = 8100
Right Hand Side = [tex]\[45^{2} + 76^{2}\][/tex]
= 2025 + 5776
= 7801
So the left hand side is not equal to right hand side. The condition for right triangle is NOT satisfied.
