Question

1. Jeff just bought a house on a triangular lot. The sides measure 85 feet, 132 feet and 157 feet

right triangle?

Answer 1

Answer is yes, it is a right triangle

Step by step

Using Pythagorean theorem

a^2 + b^2 = c^2

The two shorter sides are a + b
The hypotenuse is side c

85^2 + 132^2 = 157^2

7225 + 17424 = 157^2

24649 = 157^2

Take square root of both sides

157 = 157

Correct, it equals so it is a right triangle
