Question

the perimeter of right angle 60 degree it hypertext find the area of right angled triangle​

Answer 1

Answer:

Step-by-step explanation:

Any triangle with one of the angles equal to 90° is called a right angled triangle or simply a right triangle.

The area A of a right triangle with sides a and b is given by

A = (1 / 2) a × b

The perimeter P of a right triangle with sides a and b and hypotenuse h is given by

P = a + b + h

Using the Pythagorean theorem, we can write

h 2 = a 2 + b 2

which gives

h = √(a 2 + b 2)

Hence the perimeter can be written in terms of a and b only as follows:

P = a + b + √(a 2 + b 2)
