Answer:
x = 130 degrees
Step-by-step explanation:
Angle of right-angled triangle can be found as the sum of all angles should be 180.
65 + 90 + A = 180
A = 25
The whole angle on the second triangle can be found by 80 + 25 = 105.
The angle below x can be found by the sum again
50 + 105 + B = 180
B= 25
x can now be found by the sum again, this time of the angle below 80 (25) and the angle B below x (25)
25 + 25 + x = 180
x = 130 degrees
