Question

an angle of triangle measure 60° . the difference between measure of other two angle is 20°. is triangle a right angled triangle​

Answer 1

Step-by-step explanation:

One angle of a triangle =60

∘

Other two angles are in the ratio 2:3

Sum of other two angles =180

∘

−60

∘

=120

∘

Let one of other two angles =2x

Then third angle =3x

2x+3x=120

∘

5x=120

∘

x=24

Other two angles are 2x=2×24=48

∘

and 3x=3×24=72

∘

Other two angles of the triangle are 48

∘

,72

∘
