Question:
if the angles of a triangle are in the ratio 3:4:5, find the smallest angle in degrees
Answer:
Given angles of a triangle are in the ratio 3 : 4 : 5
Let the angles are 3x, 4x, 5x
Now, 3x + 4x + 5x = 180
=> 12x = 180
=> x = 180/12
=> x = 15
The angles are 3*15, 4*15, 5*15 = 45, 60, 75
So, the smallest angle is 45
