Question

the angle of a triangle are in ratio 3 :1:2 find the measure of largest triangle​

Answer 1

Step-by-step explanation:

sum of all angles of the triangle is 180

thus 3x + 1x + 2x is 180

6x is 180

x is 30

largest angle is 3 multiplied by 30

which is 90

Answer 2

Step-by-step explanation:

Explanation:

the sum of the angles in a triangle

=180∘

sum the parts of the ratio 3+2+1

=6 parts

180∘/6= 30∘ =1 part

3 parts =3×30∘= 90∘

2 parts = 2×30∘= 60∘

the smallest angle =30∘
