A shelf is in the shape of a triangle. Find the angles of the triangle if the measures of the angles are in the ratio x:x:4x .

Respuesta :

Sum of interior angle of a triangle is 180 degrees.
x + x + 4x = 180
6x = 180
x = 180/6 = 30
4x = 4 x 30 = 120
the measures of the angles are : 30 degrees, 30 degrees ,120 degrees
