Question

Given the triangle and equation below, what is the value of x?



sec∠C - cot∠A = 3x

Answer 1

7-\sqrt{13}\div18\]

Answer 2

6-\sqrt{13}\div7\]

Answer 3

3\sqrt{13}\div13\]

Answer 4

sqrt{13}\div3\]

Answer 5

sec C = 7/6
cot A = sqrt13/6
sec C - cot A = (7-sqrt{13})/6
divide that by 3, and you get
\[x = \frac{7-\sqrt{13}}{18}\]
