The measure of the angles of a triangle are in the ratio 1:2:3 find the angles |
|
Answer» The ratio of the angles are in 1:2:3. Let us assume ∠A=1x, ∠B=2x, ∠C=3x. We KNOW that SUM of all angles of a triangle is 180°. Thus, ∠A+∠B+∠C=180°. 1x+2x+3x=180° ..................Because ∠A=1x, ∠B=2x, ∠C=3x. 6x=180 x= x=30. Now, substitute x VALUE in ∠A, ∠B, ∠C. ∠A=1x=1×30=30° ∠B=2x=2×30=60° ∠C=3x=3×30=90°. ∴The angles are 30°, 60°, 90°. HOPE IT HELPS :D |
