Answer:

Option (3)

Step-by-step explanation:

In a right triangle,

Cosine rule → $cos(\theta)=\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

Sine rule → $sin(\theta)=\frac{\text{Opposite side}}{\text{Hypotenuse}}$

In the given triangle,

By cosine rule,

$cos(h)=\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

$cos(h)=\frac{z}{x}$

Or cos(h°) = z ÷ x

Therefore, Option (3) will be the answer.

Answer:

$\frac{7}{2}$

Step-by-step explanation:

$\frac{12-3y}{2} + y (\frac{2y-4}{y})$

we substitute the value of "y" in the equation:

$\frac{12-3(3)}{2} + 3 (\frac{2(3)-4}{3})\\\\\frac{12-9}{2} + 3 (\frac{6-4}{3})\\\\\frac{3}{2} + 3 (\frac{2}{3})\\\\\frac{3}{2} + 2\\\\\frac{7}{2}$
