Question

If one side of triangle is 120 and another is 30 find third side of triangle x

Answer 1

Answer:

Let the triangle be named ABC

Step-by-step explanation:

We are given,

AB=120

BC=30

CA=?

Solution: AB+BC+CA=180

120+30+CA=180

150+CA =180

CA =180-150

CA =30

Therefore, the third side is 30.

Answer 2

Answer:

Ans x = 30 degree

Step-by-step explanation:

As we know that a triangle all sides are equal to 180 degree.

One side of a triangle is 120 degree

Another side is 30 degree

So, third side will be = 120 + 30 + x = 180 degree

150 + x = 180 degree

x = 180 - 150

x = 30 degree
