Question

If three angles of a triangle are 2x°, 6x° and x°, find the size of largest angle.​

Answer 1

so the answer is 6x°which is equals to 120°

Explanation:

2x°+6x°+x°=180(The sum of the interior angle of the triangle is 180°)

9x°=180°

9x°÷9=180°÷9

x=20°

2x°is equals to 2×20°=40°

6x° is equals to 6×20°=120°

x° is equals to x×20°=20°
