Question

The interior angles of a triangle are related as 2:3: 7. Find the length of the longest side of the triangle if the shortest side is 1 cm long.​

Answer 1

Step-by-step explanation:

let the ratio 2:3:7 be 3x and 7x

let the shortest side be 2 ratio

hence 2=1cm

so,

According to the question,

=>1+3x+7x=180°(sum of all sides of a triangle=180°)

=>3x+7x=180-1

=>10x=179

=>x=179/10

=>x=17.9
