If angles of a triangle are in the ratio of 2 : 3 : 4, then the measure of the smallest angle is:
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e 40o.
| Understanding/Application |
|
Let the common ratio be x. 2x + 3x + 4x = 180 (angle sum property) 9x = 180 x = 20o |
| Smallest angle = 2x = 2(20) = 40o |
