Question

9. The angles of a triangle are in the ratio 1: 2: 6. Find the angles.​

Answer 1

Answer:

ALL ANGLES OF TRIANGLES ARE EQUAL TO 180 DERGREES

Step-by-step explanation:

SO

$1x + 2x + 6x = 180 \\ 9x = 180 \\ x = \frac{180}{9} \\ x = 20$

So

$first \: angle = 1 \times 20 = 20 \: deg \\ second \: angle = 2 \times 20 = 40 \: deg \\ third \: angle = 6 \times 20 = 120 \: deg$
