Question

if the angle of a triangle are in ratio 1:2:3 determine the three angle​

Answer 1

Answer:

total deree of angles =180

1 part = 180/6= 30

angle 1 = 1*30 =30

angle 2=2*30 = 60

angle 3=3*30 = 90

Step-by-step explanation:

Answer 2

Answer:

Let the angles be x

Now we will have the angles like 1x , 2x and 3x

Sum of angles of triangle is 180°.

Step-by-step explanation:

Now let's solve

1x +2x+3x=180°

6x=180°

x=180°/6

x=30°

Value of x is 30°

Now for 1st angle = 1x

=1*30

=30°

2nd angle = 2x

=2*30

=60°

3rd angle =3x

=3*30°

=90°

You can also check this solution by adding all the three angles of the sum is 180°, then it is right.
