Question

measure of angle of triangle are in ratio of 3:4:5 what
is the measure of smallest angle of triangle
O 25°
O 30
O
450
O 60°​

Answer 1

Step-by-step explanation:

ratios of a triangle are3:4:5

Answer 2

The sum of angles in a triangle is 180°

so, 3x+4x+5x= 180°

12x=180°

x = 15°

Then the angles are

3x= 3×15°=45°

4x= 4×15°= 60°

5x = 5×15°= 75°

so the smallest angle is 45°

then the answer is option C
