Question

find x, if the angles of the triangle are 2x°,3x°,4x° and also find smallest angle of that triangle​

Answer 1

Step-by-step explanation:

• Here, angles of the triangle are 2x°,3x° and 4x°.
• Now, we know that sum of angles of triangle is 180°
• 2x+3x+4x = 180
• 9x = 180
• x = 180/9
• x = 20°
• Therefore,angles of triangle are 2x = 2*20 = 40°,3x = 3*20 = 60° and 4x = 4*20 = 80°.
• So, the smallest angle = 2x = 40°.

Answer 2

Step-by-step explanation:

given, the angles are 2x,°3x°,4x°

the sum of the angles of a triangle is 180°

2x+3x+4x=180

9x=180

x=180/9

x=20

angles are 2x=2×20=40

3x=3×20=60

4x=4×20=80

the smallest angle is 40°
