Which of the following measurements could be the side lengths of a right triangle?

DaniilM [7]

Answer:

C. 10in 24in 26in

Step-by-step explanation:

Right Scalene Triangle

Side a = 24

Side b = 10

Side c = 26

Angle ∠A = 67.38° = 67°22'48" = 1.17601 rad

Angle ∠B = 22.62° = 22°37'12" = 0.39479 rad

Angle ∠C = 90° = 1.5708 rad = π/2

Area = 120

Perimeter p = 60

Semiperimeter s = 30

Height ha = 10

Height hb = 24

Height hc = 9.23077

Median ma = 15.6205

Median mb = 24.5153

Median mc = 13
