Use the Law of Cosines to find the specified missing value. Approximate your answer to the nearest tenth.
Charra [1.4K]
<h3>Answer:  176.6</h3>

Work Shown:

b^2 = a^2 + c^2 - 2*a*c*\cos(B)\\\\b^2 = 150^2 + 30^2 - 2*150*30*\cos(150)\\\\b^2 \approx 31194.22863406\\\\b \approx \sqrt{31194.22863406}\\\\b \approx 176.618879608211\\\\b \approx 176.6\\\\

Solve the system of equations using the substitution method.
Delicious77 [7]

Answer:

x = 14

y = -3

Step-by-step explanation:

Given

2x + 8y =4

x = -3y + 5

Required

Solve

Substitute x = -3y + 5 in 2x + 8y =4

2(-3y + 5) + 8y =4

Open bracket

-6y + 10 + 8y =4

Collect like terms

-6y +  8y =4-10

2y =-6

Divide both sides by 2

y = -3

Substitute y = -3 in x = -3y + 5

x = -3 * -3 + 5

x = 9+ 5

x = 14

Cosx=4/5 what is sin2x cos2x and tan2x
earnstyle [38]

Answer:

-24/5

Step-by-step explanation:

The solution to the problem is as follows:

cscx < 0 means 1/sinx < 0, or sinx < 0.  

sinx = -3/5 because you're dealing with a 3-4-5 triangle, and we established

sinx is negative.  

sin2x = 2sinxcosx = 2*-3/5*4/5 = -24/25  

cos(2x) = cos^2(x) - sin^2(x) = 16/25 - 9/25 = 5/25 = 1/5  

tan2x = sin2x / cos2x = -24/5

Answer:

A

Step-by-step explanation:

We can substract the wavength of the violet light to the wavelength of the red light:

(6.5 x 10^-7 m) - (4.0 x 10^-7 m) = 2.5 x 10^-7 m
