Answer:
7
Step-by-step explanation:
line in the middle is an angle bisector
14/6 = 21 / 3x - 12
first, cross multiply
14 (3x - 12) = 6*21
Remove the brackets
42x - 168 = 126
Add 168 to both sides
42x = 168 + 126
Combine
42x = 294
Divide by 42
x = 294/42
x = 7

cot 0=12/5 find tan 0
cot = adjacent/opp
tan = opp/adjacent
cot = 12/5
tan = 5/12
X=(6x+1)(x-1) because you are factoring out
