Answer:

25. x = 17°

26. x = 50°

Step-by-step explanation:

25. There is a straight line which means :

108 +4x = 180

solving the obtained equation

108+4x = 180

4x = 180 - 108

4x = 72

x = 72/4

x = 17°

26. Again we can see that the angles in which 101 and x + 29 exists is a straight line . which means :

101 + x + 29 = 180

101 + 29 + x = 180

130 + x = 180

x = 180 - 130

x = 50°

So the answer of question no. 25 is 18 degree.

The answer of question no 26 is 50 degree.
