Question

In triangle ABC, the measures of angles A, B, and C, respectively, are in the ration 1:2:3. Find the measure of each angle

Answer 1

the answer is (<A=30° <B=60° <C=90°)

Explanation:

in ∆ABC

<A,<B<C, are in ratio to one another in form of 1:2:3

total ratio =1+2+3=6

so,we say

<A=1/6×180=1×30=30°

<B=2/6×180=2×30=60°

<C=3/6×180=3×30=90°
