Question

6. The angles of a triangle are in the ratio 3:1:2. Find the angles.
(Hint: Sum of three angle of triangle is 180°)​

Answer 1

Step-by-step explanation:

let 1st angle be 3x

let second angle be x

let third angle be 2x

=> 3x + x + 2x = 180° (sum of angles of a triangle is 180°)

=> 6x = 180°

=> x = 180/6.

=> x = 30°

So, the angles of a triangle are :-

★ 3x = 3 (30) = 90°

★ x = 30.

★ 2x = 2 (30) = 60°

Answer 2

Answer:

$3x + 1x + 2x = 180 \\ 6x = 180 \\ x = \frac{180}{6} \\ x = 30 \\ 3x = 3 \times 30 = 90 \\ 1x = 1 \times 30 = 30 \\ 2x = 2 \times 30 = 60$

here is your answer
