Let's solve ~

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:7 \sec(x) - 7 = 0$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:7 \sec(x) = 7$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: \sec(x) = 7 \div 7$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: \sec(x) = 1$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:x = 0$

Answer:

Step-by-step explanation:

Using the tangent ratio in the right triangle

tanC = $\frac{opposite}{adjacent}$ = $\frac{AB}{BC}$ = $\frac{c}{a}$ , then

C = $tan^{-1}$ ( $\frac{c}{a}$ )
