Question

three angles of a triangle are X degree 2x degree and 3X degree prove that the triangle is a right angle​

Answer 1

Answer:

Step-by-step explanation:

x+2x+3x=180        (angle sum property)

6x=180

x=180/6

x=30

substitute x in the angles

x=30

2x=60

3x=90

since one of the angles is 90

the triangle is a right triangle

Answer 2

Answer:

30

Step-by-step explanation:

x+2x+3x we get the answer 30

because sum of amgles of a triangle is 180degrees
