Question

in a triangle ABC angle A=3 angle B, angle B= angle C upon2 . find the angles of triangle​

Answer 1

Solution

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 180o

Hence ∠A+∠B+∠C=180o

⇒3∠C+2∠C+∠C=180o

⇒∠C=30o

∴∠A=900,∠B=60o,∠C=30
