The hypotenuse of a right-angled triangle 18 meters, one of its corners 60 degrees, find the legs.

Since the triangle is rectangular, one angle will be equal to 90 degrees, the second angle will be 60 degrees (written in the statement), it is easy to guess that the third angle is equal to 30 degrees. We know that the side opposite the 30 degree angle is half the hypotenuse. We get 18: 2 = 9
9 meters – first leg
Further we will use the Pythagorean theorem (the square of the hypotenuse is equal to the sum of the squares of the legs)
18 squared – 324
9 squared – 81
324-81 = 243
The answer would be 9 meters and √243
