Answer:
x = 145 degrees
Step-by-step explanation:
In leftmost triangle, missing angle :
= 180 - (90 + 35)
= 55 degrees
Top angle of middle triangle :
= 180 - (60 + 55)
= 180 - 115
= 65 degrees
Bottom angle of middle triangle :
= 180 - (90 + 65)
= 25 degrees
Linear pair
= 180 - 25
=> x = 145 degrees
