Question

the triangle are in the ratio 1 ratio 2 ratio 1 find the value of the greatest angle​

Answer 1

Step-by-step explanation:

1:2:1

1x+2x+1x = 180°

4x = 180°

x = 180/4 = 45°

2x being the greatest is 2×45° = 90°

Answer 2

Answer:

Let thier ratio be 1x,2x,1x

According to the question

1x+2x+1x=180°[angle sum property]

4x=180

x=180/4

therefore x=45°

Therefore greatest angle =45×2

=90°
