Find the missing length to the nearest tenth.
A right triangle has a left side of 3 units and a lower side of 12 units which meet at the right angle. The side opposite of the right angle measures h units.
A. 9
B. 144
C. 11.6
D. 12.4
Using the Pythagorean theorem:
h^2 = 3^2 + 12^2
h^2 = 9 + 144
h^2 = 153
h ≈ 12.4
Therefore, the missing length is D. 12.4 units.
