Question

If the measures of the angles of a triangle are in the ratio. 1:2:3 and if the length of the smallest side of the triangle is 10cm, then the length of the longest side is

A) 20cm B) 22cm C) 24cm D) 18cm

Answer 1

Answer:

A) 20cm

Step-by-step explanation:

Let angle = x,2x,3x

x+2x+3x=180

(∵ Sum of internal angle of a △)

6x=180∘

x=30∘

So, angle = 30, 60, 90

Smallest side of △ =

1 Unit=10cm

Largest side of △ = 2 units = 20 cm
