Question

The angle of a triangle is x 3x and 5x find x

Answer 1

Answer:

x= 30°

Step-by-step explanation:

sum of angles of a ∆ = 180

then adding 3 angles,

x + 3x + 5x = 180

=>6x =180

x= 180/6

x = 30°

Answer 2

Answer:

20°

Step-by-step explanation:

sum of three angles in a triangle =180°

so, x+3x+5x=180°

9x=180°

x=20°
