Apply the 30-60-90 triangle theorem to find the length of the shorter leg of a triangle if the length of the hypotenuse is 20 cm

The shorter side is of measurement of 10 cm.

Given that:

The length of the hypotenuse = 20 cm.

The triangle has its angle as 30, 60 and 90 degrees.

Since the given triangle is a right angle, thus we can use trigonometric ratios.

Taking the 60 degree angle we will have:

Similarly,

Thus, the shorter side is base with the measurement of 10 cm.

10 cm

Step-by-step explanation:

Let shorter leg = x

Hypotenuse = 2x

To find the length of the short leg it is 20/2 = 10

assuming you mean addition: addition and subtraction are reverse operations.
