Answer:

11.4

Step-by-step explanation:

Add 5+8+2

You get 15

So 15x

Then subtract 9 from 180.

180 minus 9 is 171

Divide by 15

You get 11.4

Answer:

B.11.4

Step-by-step explanation:

The sum the 3 angles of a triangle add to 180 degrees

5x+8x+2x+9 = 180

15x+9 =180

Subtract 9 from each side

15x+9-9 =180-9

15x = 171

Divide by 15

15x/15 =171/15

x =11.4

Problem is attached, need to use sin and cosine formulas
Tatiana [17]

In triangle 1, the values are α = 65°, a = 42.02, and 45.66. And in triangle 2, the values are β = 55.74, γ = 84.26, and c = 10.84.

<h3>What is the law of sines?</h3>

For any triangle ABC, with side measures |BC| = a. |AC| = b. |AB| = c,

we have, by law of sines,

\dfrac{\sin \alpha }{a} = \dfrac{\sin \beta }{b} = \dfrac{\sin \gamma}{c}

1.  β = 15°, γ = 100°, and b = 12, then the missing side and angle will be

The sum is 180° of a triangle. Then the value of α will be 65°.

\dfrac{\sin 65^o}{a} = \dfrac{\sin 15^o}{12} = \dfrac{\sin 100^o}{c}

Then the value of a will be

a = 42.02

Then the value of c will be

c = 45.66

2.  α = 40°, a = 7, and b = 9, then the missing side and angle will be

(sin 40°)/7 = (sin β) / 9

       sin β = 0.82644

             β = 55.74

The sum is 180° of a triangle. Then the value of γ will be 84.26°.

Then the value of c will be

c = 10.84

If g(x)=|x-3|, find the values of g(3) and g(-3)
agasfer [191]
Plug in what ever value is the function of g for x and solve:
g(3) = |3-3| = |0| = 0
g(-3) = |(-3)-3| = |(-6)| = 6

Hope this helps :)
