I think its C Because Aob is a given angle Boc is where we prove Aob so Im 95% sure its c
Answer:
X=17
Step-by-step explanation:
AC^2=AB^2 +BC^2(PYTHAGOREAN THEORM)
100=64 +BC^2
36=BC^2
6CM=BC
AD^2=AB^2+BD^2(PYTHAGOREAN THEORM)
X^2 =64+225
X^2=289
X=17
The answer should be 3x-1 depending on if thats 3x^2 or 3*2 but im guessing its 3 times 2 so your answer should me 3x-1
