Question

Find the perimeter of the triangle.

Answer 1

in triangle

b=√(37²-12²)=35

perimeter of the triangle.=sum of all side

=37+12+35=84in

Answer 2

9514 1404 393

Answer:

84 in

Explanation:

The Pythagorean theorem is used to find the length 'b'.

b^2 +12^2 = 37^2

b = √(37^2 -12^2) = √1225 = 35

Then the perimeter is the sum of side lengths:

P = a + b + c = 12 + 35 + 37

P = 84 . . . inches
