You’re given two side lengths of 3 centimeters and 5 centimeters. Which measurement can you use for the length of the third side to construct a valid triangle?
8 centimeters
6 centimeters
4 centimeters
10 centimeters
2 centimeters

its 4 because if you take 3 squared which is 9 and 5 squared which is 25 which is also the hypotenuse the missing leg is 4 because 4 squared is 16 and 16+9=25 so that satisfy the Pythagorean theorem

Step-by-step explanation:

I explained on top and please give me the brainliest

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
