Question

Construct a triangle ABC whose perimeter is 9cm and ratio among the length of its sides is 1:3:5​

Answer 1

Answer:

Step-by-step explanation:

Let the angles be 3x, 4x and 5x

Therefore,

The sum of all the angles of a triangle are = 180 degrees

Therefore,

3x + 4x + 5x = 180

12x = 180

x = 15

The angles should be (3 × 15) , (4 × 15) , (5 × 15)

Therefore ,

The angles are 45, 60, 75.

Therefore now construction,

Draw a triangle ,

Taking AB as 3cm

Draw two arcs one of 60 and one of 45

Make a Triangle using the angles given
