Question

In three angel of a triangle are in the into 3:7:10 show that triangle is right angel

Answer 1

Let the angles of triangle be 3x, 7x, 10x.

Sum of angles of triangle = 180

3x+7x+10x=180

20x=180

x=9

Angles = 3*9=27, 7*9=63, 10*9=90.

Since, one angle is 90 therefore, triangle is right angled..
