Cost price of a TV set = $900

Selling price of this TV set = $1125

Since Selling price > Cost Price, Alex had a profit.

Profit earned by Alex :

$= \tt \: Selling \: price - Cost \: price$

$= \tt1125 - 900$

$=\tt \$225$

Thus, the profit Alex made = $225

We know that :

$\color{hotpink}\tt \: Profit \: percentage =\color{plum} \frac{profit \times 100}{cost \: price}$

Percentage of profit alex earned :

$= \tt \frac{225 \times 100}{900}$

$=\tt \frac{22500}{900}$

$\color{plum}= \tt25\%$

Thus profit percentage = 25%

Therefore, percentage of profit Alex earned by selling the TV set = 25%

${ \bf{ \sec( \theta) = \frac{10}{6} }}$

Step-by-step explanation:

${ \boxed{ \bf{ \cos( \theta) = \frac{adjacent}{hypotenuse} }}}$

Adjacent = 6

Hypotenuse = 10

${ \sf{\sec( \theta) = \frac{1}{ \cos( \theta) } }}$

therefore:

${ \sf{ \sec( \theta) = \frac{hypotenuse}{adjacent} }} \\ \\ { \sf{ \sec( \theta) = \frac{10}{6} }}$
