In a triangle ABC, if 2 angle a=3 angle b=6 angle c,determine angle A |
|
Answer» Step-by-step explanation: ACCORDING to the CONDITION in the △ABC, 2∠A=3∠B=6∠C ⇒∠A=3∠C and, ∠B=2∠C Sum of interior ANGLES of the triangle is 180 o
Hence ∠A+∠B+∠C=180 o
⇒3∠C+2∠C+∠C=180 o
⇒∠C=30 o
∴∠A=90 ,∠B=60 o ,∠C=30 o
