Question

Find the unknown side of the triangle

Answer 1

if you use the hypotenuse formula

`c = \sqrt{a ^(2) + {b}^(2) }`

a = 12

b = 16

now input the values and solve for c

`c = \sqrt{ {12}^(2) + {16}^(2) }`

`c = √(144 + 256)`

`c = √(400)`

Square root of 400 = 20

so the long side is 20

Answer 2

x=20

Explanation:

12^2 + 16^2 = 400

square root of 400 = 20
