Answer: x = 115 degrees
Step-by-step explanation:
a triangle we know all angles had up to 180 degrees
for the first triangle we have 65 + 90 = 155 then we do 180 - 155 = 25
so for the small triangle one angle is 25 degrees
now for the other triangle we have 80 + 60 = 140 then 180 - 140 = 40
so now we have all angles except x and to find that we do 25 + 40 = 65 then to find x do 180 - 65 = 115
