Angle BCA = 180 - 100
angle BCA = 80
Isosceles triangle ABC has two congruent angles, A and B
2x + 80 = 180
2x = 100
Angles A and B = 50 or y and z = 50
I think lines AB and DE are supposed to be parallel, so angles y and x are consecutive interior angles (supplementary)
x = 180 - 50 = 130
What convention had more than 2,500 people attending?
Answer:
60
Step-by-step explanation:
You dont have enough infor, but if its 120 degrees, A total degree of a triangle is 180, so 180-120 equals 60
