Question

all angles of triangle ABC are same.if CA=5.5 cm then find CB​

Answer 1

Answer:

Required answer is CB = 5.5cm

Step-by-step explanation:

Sum of three angles of a triangle is 180°

If all the angles are same then every angle should be 180°/3 = 60°

Now we know a triangle having three equal angles is  equilateral triangle.

Hence the Given triangle is equilateral triangle.

In  equilateral triangle length of each side is same with each other.

now , in ΔABC if CA = 5.5 cm and CA=AB=BC             [∵ΔABC is equilateral  

                                                                                          triangle]

Then CB = 5.5 cm (Ans.)
