Answer:

Step-by-step explanation:

Sum of interior angles of a triangle is 180degree.

2x + 105 + 31 = 180

2x = 44

x = 22

Answer:

The given Angles in triangle are 105° , 31° & 2x°

we have been asked to find the value of x .

We Know Sum of all three angles in a triangle is 180°

Now Let's put the given value we obtain

105° + 31° + 2x = 180°

136° + 2x = 180°

2x = 180° - 136°

2x = 44

x = 44/2

x = 22°

So, the value of x is 22°.
