The angles of a triangle are in the ratio of 3 : 4 : 8. The triangle is :
Answer & explanation
Correct answer: option 3
We know that,
The sum of all angles of a triangle is 180°
We have,
The ratio of angles of a triangle is 3: 4 : 8
Let the values of angles be 3x, 4x and 8x
3x + 4x + 8x = 180°
15x = 180°
= x = 12°
3x = 36° , 4x = 48° and 8x = 96°
One of the angles is more than 90°
Then, the triangle will be obtuse angle triangle.
