pentagon [3]

Answer:

The answer is " $\frac{A}{(x-2)} + \frac{B}{(x+3)}$ "

Step-by-step explanation:

Let the given value is: $\frac{x-6}{x^2+x-6}$

$\to \frac{x-6}{x^2+x-6}=\frac{x-6}{x^2+(3-2)x-6}\\\\$

$=\frac{x-6}{x^2+(3-2)x-6}\\\\ =\frac{x-6}{x^2+3x-2x-6}\\\\ =\frac{x-6}{x(x+3)-2(x+3)}\\\\ =\frac{x-6}{(x+3)(x-2)}\\\\=\frac{A}{(x-2)} + \frac{B}{(x+3)}$

The measurement of an angle of a right triangle is 40° and the leg opposite to this angle is 5 cm long. what is the length, in c

8090 [49]

Sine 40 = 5 / hypotenuse
0.64279 = 5 / hypotenuse
hypotenuse = 5 / 0.64279
hypotenuse = 7.7786
tangent (50) = opp / adj
tangent (50) = opposite / 5
1.1918 * 5 = opposite
opposite side = 5.959
