Answer:
A) 14
Step-by-step explanation:
BC is congruent to DC in saying this you can plug the equations to each other and solve for y and then put its back into the equation for BC to get the length.
3y+5=5y-1
subtract 3y from both sides --> 5=2y-1
add 1 to both sides --> 6=2y
now get y alone, divide by 2 by both side --> y=3
plug y in back to 5y-1 --> 5x3-1
15-1
BC = 14
The Anwser Is 0.4 Which Is B
Apply in this order Ι-15Ι - 33÷11= 15-3=12
Good luck!!!

Take 145-115 because for this your supposed to add all numbers inside to get exterior angle so you would do 145-115=30
R would be 30
R=30
Hope this helps
