Question

Construct a ∆ABC with BC = 5 cm and sum of other two sides is 12 cm and the ratio of AC AB is 2 : 1.​

Answer 1

Answer:

All the sides of triangle are :

AB = 8 cm , BC = 5 cm , AC = 4 cm

Step-by-step explanation:

GIVEN ,

BC = 5 cm

Ratio of other two sides = 2:1

Sum of other two sides = 12

Let the other two sides be 2x and 1x.

Since x is the constant by which the numbers are divided.

So According To the Question,

2x + 1x = 12

3x = 12

x = 4

So,value of x = 4

Now other two sides,

AB = 2x = 2×4 = 8 cm

AC = 1x = 1×4 = 4 cm
