Question

Find the unknown side of the triangle

Answer 1

Answer:

if you use the hypotenuse formula

$c = \sqrt{a ^{2} + {b}^{2} }$

a = 12

b = 16

now input the values and solve for c

$c = \sqrt{ {12}^{2} + {16}^{2} }$

$c = \sqrt{144 + 256}$

$c = \sqrt{400}$

Square root of 400 = 20

so the long side is 20

Answer 2

Answer:

x=20

Step-by-step explanation:

12^2 + 16^2 = 400

square root of 400 = 20
