Question

if three angles of a triangle are in the ratio of1:2:6 find their measures what type of triangle is it​

Answer 1

Let the Angles be x°, 2x° and 6x°

ATQ,

x + 2x + 6x = 180 [ According to Angle Sum Property of Triangle ]

9x = 180

.

Angle 1 = 20°

Angle 2 = 2*20 = 40°

Angle 3 = 6* 20 = 120°

It's an Obtuse Triangle, as one of the angles is more than 90° the sum of other two angles less than 90°
