Answer :
- 45⁰ is the measure of the smallest angle of a triangle
Given :
- The measure of angles of a triangle are in the ratio 3 : 4 : 5
To find :
- Smallest angle of triangle
Solution :
- Let the ratio be 3x , 4x and 5x
As we know that,
- Sum of all angles in a triangle is equal to 180⁰
According to question,
》3x + 4x + 5x = 180⁰
》12x = 180⁰
》x = 180⁰/12
》x = 15
Now we have to find the smallest angle of a triangle:
- 3x = 3(15) = 45⁰
- 4x = 4(15)= 60⁰
- 5x = 5(15) = 75⁰
Hence , 45⁰ is the measure of the smallest angle of a triangle

- The measure of the smallest angle of the triangle.
Let the angles of the triangle be 3x,4x and 5x
Therefore,
So, the angles will be :
Hence, we can see that the smallest angle is 45°.
So our answer will be
