Answer:
OK wait I have no clue I would be able to help you but you have to put in the "Diagram" so I can solve for all angles, anyways it's been 10 minutes but I found where this question came from: Khan Academy 8th grade illustrative unit 1 lesson 16 Parallel lines and the angles in a triangle, the graph I see has an answer of 37
Step-by-step explanation:
Answer is correct on Khan Academy:
Solve for angle c 41+102=143 180 degrees in a full triangle so you need to do
180-143 to get 37 NOW 37 is the right answer I have put in a lot of effort to get this answer to you anyways to prove it is right 3 ways I will test it by finding the value of every angle and here is the math for that 37+37+102+41+143
A=143 because 102+41 angle DB is 43 because there is one line intersecting the two parallel lines, this means that the angle is also using the same two lines is also 41.
Then 37 was the only two numbers that could be added to get the full 360.
Answer: 37
Here is a screenshot =D
This was a lot of effort for one 8th grader so if this is sloppy please forgive me.
