One of the corners of a right-angled triangle = 60 degrees, and the sum of hypotinus = 18 cm, find the hypotinus and the smaller leg.
If the first angle = 60 °, the right angle = 90 °, hence the third = 30 °
We use the property of a right-angled triangle.
The smaller leg opposite the 30 ° angle is equal to half the hypotenuse, hence:
x + 2x = 18,
x = 6 cm.
6 * 2 = 12 cm.
Answer: 6 cm leg, 12 cm hypotenuse.
