Question

if the sizes of the angles of a triangle are 3x,4x and 5x. find the smallest angle of the triangle. please solve with solution..

Answer 1

Answer:

sum of angles is180

then according to question

3x+4x+5x=180

then 12x=180 X=15

then the smallest angle is 3x the angle is45

Answer 2

Given :

• First Angle = 3x

• Second Angle = 4x

• Third Angle = 5x

________________

To Find :

• Smallest Angle

________________

Solution :

We know that, Angle sum of property :

⇒ Sum of angles = 180°

⇒ 3x + 4x + 5x = 180°

⇒ 3x + 9x = 180°

⇒ 12x = 180°

⇒ x = 180°/12

⇒ x = 15°

➜ Smallest Angle = 3x = 3(15) = 45°
