What is the value of x
what is the value of x?

The value of x is:

                            28°

We know that the sum of all the three angles of a triangle is equal to 180 degree.

The three angles of a triangle here are: x°,95° and 57°

Hence, by the property of triangles we have:

x°+95°+57°=180°

i.e.

x°+152°=180°

on subtracting both side by 152 degree we have:

x°=180°-152°

x°=28°

         Option: A is the correct answer.

                           A.   28°
