\sf \red⇛ \green {3a + 1 = 16}

Move the constant to the right-hand side and change its sign to minus sign since it is in plus

\sf \red⇛ \green{3a = 16 - 1}

Subtract the numbers

\sf\red ⇛ \green{3a = 15}

Divide both sides of equation by 3

\sf \red⇛ \green{a = 5}

  • On observing the above steps, Option B is correct!

=> BC is hypotenuse.

=> BC = AC x BC/AC = AC/(AC/BC) =AC/cosC.

That's the way we've done!
