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.
