If sine ⁡theta equals negative 8/17 and the terminal side of theta lies in quadrant IV, find cosine ⁡ theta .
Lelechka [254]
\sin^2\theta+\cos^2\theta=1\implies \cos\theta=\pm\sqrt{1-\sin^2\theta}

Since \sin\theta=-\dfrac8{17}, it follows that

\cos\theta=\pm\sqrt{1-\dfrac{64}{289}}=\pm\sqrt{\dfrac{225}{289}}=\pm\dfrac{15}{17}

where the sign depends on the location of the terminal side of the angle. Since the terminal side lies in the fourth quadrant, that means the cosine of the angle is positive, so

\cos\theta=\dfrac{15}{17}

I’m failing math help plssss
puteri [66]

Answer:

Step-by-step explanation:

L and W are the length and width of the flag.

"The perimeter of the flag is 500 feet"

2L + 2W = 500

L+W = 250

"The length is 30 feet greater than the width"

L = W+30

You have a system of two equations:

L+W = 250

L  = W+30

Substitute W+30 for L:

(W+30) + W = 250

2W + 30 = 250

2W = 220

W = 110 ft

L = W+30 = 140 ft

:::::

"C is 400 miles longer than D"

C = D+400

"The sum of their lengths is 5,580 miles"

C + D = 5,580

You have a system of two equations:

C = D+400

C + D = 5,580

Substitute D+400 for C:

(D+400) + D = 5,580

2D + 400 = 5,580

D = 2,590 miles

C = D+400 = 2,990
