There is a negative 1/sin(a) and a positive 1/sin(a), so we can cancel both of them out.

We have

1/csc(a) - cot(a) = -1/csc(a) + cot(a) remaining.

One is positive, and one is negative, and they are both equal, so we can also cancel each of them out.

We have

0 = 0 left.

0 equals 0, so we are done explaining.

Hope this helped

Answer:

x = 12

Step-by-step explanation:

Reference angle = 45°

Opposite side length = x

Hypotenuse = 12√2

Thus, to find x, apply trigonometric ratio.

$sin(45) = \frac{x}{12\sqrt{2}}$

Multiply both sides by 12√2

$sin(45)*{12\sqrt{2}} = x$

$\frac{1}{\sqrt{2}}*{12\sqrt{2}} = x$ (sin 45 = 1/√2)

$\frac{1*12\sqrt{2}}{\sqrt{2}} = x$

$\frac{12\sqrt{2}}{\sqrt{2}} = x$

12 = x

x = 12

Answer:

Step-by-step explanation:

${x}^{2} = {4}^{2} \\ = 16\\ 4y = 4 \times - 3 \\ 4 \times - 3 = - 12 \\ 16 - - 12 =16 + 12 \\ - \times - = + \\ 16 + 12 = 28 \\ 28 \div 2 = 14$
