I believe that answer is B. (The second one)
Hope this helped !!
Answer:
x = 65
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
subtract the sum of the 2 given angles from 180° for third angle
third angle = 180° - (60 + 55)° = 180° - 115° = 65°
65° and x are vertical angles and are congruent, thus
x = 65
The little marks on the sides tell that this is a equilateral triangle, each angle measures 60 degree.
2y=60
y=30
25x-15=60
25x=75
x=3
X = 180 - 121 = 59°
y = 180 - 144 = 36°
n = (x+y) = 59 + 36 = 95°
Answer is С. 95°
The anwser would be 3y-6=x
