Question

Find X, if the angles of a triangle have measured (x+40°), (2x+20°), And 3x.And also state the type of triangle it is​

Answer 1

the current answer it so you 120 triangle so you can put it 120 is a dancer

Answer 2

Answer:

We know That , The sum of three angles of a triangle is 180°.

thus,

$(x + 40) +( 2x + 20) + 3x = 180 \\ 6x + 60 = 180 \\ x + 10 = 30 \\ x = 20$

Here, We found that x = 20.

Therefore, The 3 angles are ,

$x + 40 = 20 + 40 = 60 \\ 2x + 20 = 40 + 20 = 60 \\ 3x = 60$

Three angles are 60°,60°,60°

We know that in an Equilateral triangle , All angle are 60°.

Therefore, Answer is -

x = 20 and The angle is Equilateral Triangle.
