Question

5] If the angles of a triangle are in the
ratio 3:7: 8 then the greatest angle
in radian is​

Answer 1

Answer:

The ratio of angles of triangles are 3:7:8

Let the measures of triangles are 3x,7x,8x.

⇒  3x+7x+8x=180o         [ Sum of angles of triangle is 180o ]

⇒  18x=180o

⇒  x=18180o=10o

⇒  3x=3×10o=30o

⇒  7x=7×10o=70o

⇒  8x=8×10o=80o

∴  Greatest and the smallest angles are 80o and 30o.
