YZ = 16. The triangles are congruent. This would be AAS so YZ = 16 because of CPCTC.
Hey there Gary!
If Angle DBC is 73, you do subtract it from 180 to get ABD.
180 - 73 = 107
Angle ABD = 107
Angle DBC = 73
Angle ABD > DBC
or
Angle DBC < ABD
The line BD/DB is the same length in both angles, proving line AD is greater than CD. This is also justified by the fact that lines AB and CB are congruent.
I hope this helps, let me know if there's something wrong about my answer.
I could be wrong but I think it’s 787 (786.5 but rounded would be 787)
Answer:
Step-by-step explanation:
I don't know what the answer is if I am not given choices, but here is one possibility.
2(x^2 - 12x - 7)
You could factor what is inside the brackets.
2(x - 12.557) (x + 0.557)
