Question

The perimeter of a Δ ABC is 6 times the A.M of the sines of its angles if the side "a" is 1, then the angle A is

Hint:

### if a triangle has sides a, b, and c, then the perimeter of that triangle will be P = a + b + c . In this question, we have to find value of if the side "a" is 1, then the angle A = ?.

## The correct answer is:

If a triangle has sides a, b, and c, then the perimeter of that triangle will be P = a + b + c

A.M of the sines of its angles =

According to question, The perimeter of a Δ ABC is 6 times the A.M of the sines of its angles.

so, a + b + c = 6 x

a + b + c = 2 x ( ) { }

If a triangle has sides a, b, and c, then the perimeter of that triangle will be P = a + b + c

A.M of the sines of its angles =

According to question, The perimeter of a Δ ABC is 6 times the A.M of the sines of its angles.

so, a + b + c = 6 x

a + b + c = 2 x ( ) { }

The angles of the triangle ABC are denoted by A, B, C and the corresponding opposite sides by a, b, c.

### The sides of a triangle are and for some .Then the greatest angle of the triangle is

The **law of cosines** generalizes the Pythagorean formula to all triangles. It says that *c*^{2}, the square of one side of the triangle, is equal to *a*^{2} + *b*^{2}, the sum of the squares of the the other two sides, minus 2*ab* cos *C*, twice their product times the cosine of the opposite angle. When the angle *C* is right, it becomes the Pythagorean formula.
