What is the value of y?

y=65

Step-by-step explanation:

When 2 angles are the same, it means that this triangle is an isoceles triangle. If you add up all the angles in a triangle, it must add up to 180 degrees.

180-130=50

y+y+50=180

180-50=130

130/2=65

y=65

To check:

65+65+50=180

Hope this helps!

y = 65 degrees

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.
