Answer:

8x^3-7x^2-11x+9

Step-by-step explanation:

(8x^3-5x-1)-(7x^2+6x-10)

remove unnesasary ( )

8x^3-5x-1 -(7x^2+6x-10)

the distribute

8x^3-5x-1 -7x^2-6x+10

combine like terms

8x^3-11x+9-7x^2

use the communative property to reorder the equation

Paha777 [63]

Answer:

See explanation

Step-by-step explanation:

Given

The attached triangle

Required

Complete the ratios

(a) sin B

$\sin(B)$ is calculated as:

$\sin(B) = \frac{Opposite}{Hypotenuse}$

$\sin(B) = \frac{b}{c}$

(b) cos B

$\cos(B)$ is calculated as:

$\cos(B) = \frac{Adjacent}{Hypotenuse}$

$\cos(B) = \frac{a}{c}$

$\tan(B)$ is calculated as:

$\tan(B) = \frac{Opposite}{Adjacent}$

$\tan(B) = \frac{b}{a}$

(d) tan A

$\tan(A)$ is calculated as:

$\tan(A)= \frac{Opposite}{Adjacent}$

$\tan(A) = \frac{a}{b}$

(e) cos A

$\cos(A)$ is calculated as:

$\cos(A) = \frac{Adjacent}{Hypotenuse}$

$\cos(A) = \frac{b}{c}$

(f) sin A

$\ain(B)$ is calculated as:

$\sin(B) = \frac{Opposite}{Adjacent}$

$\sin(B) = \frac{a}{c}$
