Question

Q19 If one angle of a trigle measures 2x°, the second angle 3x° and
the third angle 4x°,fin ne measure of the each angle. what is answer ​

Answer 1

Answer:

angle of a triangle is 180°

so ,the first angle is 2x°

second angle is 3x°

third angle is 4x°

so according to angle sum property

3x+4x+5x=180°

12x=180°

so, x=15°

so first angle be 3(x)=3×15=45°

second angle be 4(x)=4×15=60°

third angle be 5(x)=5×15=75°
