Use the Pythagorean theorem to find a whole number estimate of the length of the unknown side of the right triangle. The length
of the unknown side of the triangle is approximately cm.
1 answer:
Answer:
12 cm
Step-by-step explanation:
Leg of one side = 5 cm
Hypotenuse = 13cm
According to the theorem,
A^2 + B^2 = C^2
5^2 + B^2 = 13^2
25 + B^2 = 169
Subtract 25 form both sides,
B^2 = 169 - 25
B^2 = 144
B = sqrt( 144 )
B = 12
