Answer:
11.4
Step-by-step explanation:
<em>A</em><em>N</em><em>S</em><em>W</em><em>E</em><em>R</em>
x=24
Step-by-step explanation:
x+180+156=360
180+156=336
x+336=360
x=360-336
x=24
Assuming T, B and N are all on the same line, then we can say
BT + TN = BN
which is the segment addition postulate.
Subtract TN from both sides to get
BT + TN = BN
BT + TN - TN = BN - TN
BT = BN - TN
BN - TN = BT
Which is what choice C is saying. Therefore the answer is choice C.
