Evaluate the expression

AURORKA [14]

Answer: C) tan(pi/56)

=============================================

Explanation:

I recommend using a trig identity reference sheet. The specific identity we will be using is $\frac{\tan(A)-\tan(B)}{1+\tan(A)\tan(B)} = \tan(A-B)$

What we are given is in the form $\frac{\tan(A)-\tan(B)}{1+\tan(A)\tan(B)}$ with A = pi/7 and B = pi/8

A-B = (pi/7)-(pi/8)

A-B = pi(1/7-1/8)

A-B = pi(8/56 - 7/56)

A-B = pi*(1/56)

A-B = pi/56

Therefore,

$\frac{\tan\left(\pi/7\right)-\tan(\pi/8)}{1+\tan(\pi/7)\tan(\pi/8)} = \tan\left(\pi/56\right)$

Which expression has the same value as 59.2 - 84.7?

timama [110]

Answer:

-25.5

Step-by-step explanation:

Hi Baby girl,

59.2 - 84.7 can be worked out this way:

First calculate 84.7 - 59.2 on your rough paper

That gives 25.5

Finally make your answer a negative number (since the question is about subtracting a larger number from a smaller number)

The answer therefore is -25.5

Use the diagram below to match the ratios below. B a A b sin B COS B tan B tan A COS A sin A

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:

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

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

Switch the second equation to equal y so...
y=-2x-3
then plug in for y in the first equation
2x+4(-2x-3)=6
2x-8x-12=6
-6x=18
x=-3
now plug in for y
2(-3)+y=-3
-6+y=-3
y=3

answer (-3,3)
