The triangle to the left with all sides 5 is an equilateral triangle will have all angles 60.
The triangle to the right is a right triangle which satisfies the Pythagorean theorem and since the two sides are 5 the opp. angles are equal, making them 45 degrees each.
The third triangle in the centre (with no measurements of the sides) will have angles 45, 60 and x (applying the property that when two lines intersect the pair opp. angles are equal)
Therefore, x + 45 + 60 = 180. So, x= 75.

Hi,
Thank you very much for the explanation. If possible for you, kindly explain with picture or if someone else can do that.
