Another combination is 6 dimes and 1 nickel.

A third is 2 quarters, 1 dime, and 1 nickel.

The list goes on.

How do I use the cosine rule for these problems?
Elenna [48]

Answer:

see explanation

Step-by-step explanation:

Using the Cosine rule

a² = b² + c² - 2abcosA ← Rearranging for cosA gives

cosA = \frac{b^2+c^2-a^2}{2ab}

(a)

let a = 10, b = 7, c = 8 and A = α, then

cosα = \frac{7^2+8^2-10^2}{2(7)(8)} = \frac{49+64-100}{112} = \frac{13}{112}, thus

α = cos^{-1}( \frac{13}{112} ) ≈ 83° ( to the nearest degree )

(b)

let the angle opposite side 7 be x

Using the Sine rule

\frac{10}{sin83} = \frac{7}{sinx} ( cross- multiply )

10sinx = 7sin83 ( divide both sides by 10 )

sinx = \frac{7sin83}{10} , thus

x = sin^{-1} ( \frac{7sin83}{10} ) = 44°

The third angle can be found using the sum of angles in a triangle

third angle = 180° - (83 + 44)° = 180° - 127° = 53°

The 3 angles are 83°, 44°, 53°

I need help with how to find 2 equations for thy problem
Mrrafil [7]
To know how to find the answer you these two equations you figure out what the line is solid or dash.
Then you find the slope y-int form for the first equation and repeat for the second.
For your equation it would be y > 2x+2 and the second equation would be y> or equal to -1x+0
