Answer:
20.8 cm
Step-by-step explanation:
The term "hypotenuse" suggests this triangle is a right triangle. Then the other leg can be found using the Pythagorean theorem:
x^2 +12^2 = 24^2
x^2 = 576 -144 = 432
x = √432 ≈ 20.8 . . . cm
The other leg is about 20.8 cm.

<em>Additional comment</em>
A right triangle with a short leg that is 1/2 the length of the hypotenuse is the "special" 30°-60°-90° right triangle. The longer leg is √3 times the length of the short leg: 12√3 ≈ 20.8 cm.
You're given two angles and the side not between them are congruent, so the AAS theorem applies. (2nd selection)
<span>9540000 = 9x1000000 + 5x100000 + 4x10000
= 9x10^6 + 5x10^5 + 4x10^4</span>
In this problem the big angle will be equal to two times the smaller angle so the correct expression is:
Now we can rewrite the equation so:
