Question

If 2 angle A=3 angle B =6 angle
C of a triangle in a ∆ABC.find all angles of the triangle​

Answer 1

Answer:

Given: 2<A=3<B=6<c

then,

2<A=6<c

=> <A=6÷2<c

=> <A=3<c

3<B=6<C

=> <B = 6÷3<C

=> <B=2<C

Hence,

<A+<B+<C=180° (Angle sum Property)

= 3<C+2<C+<C=180°

=6<C=180°

=<C=180°÷6=30°

Then,

<A=3<C=3×30°=90°

<B=2<C=2×30°=60°.
