If the length of side a is 12 centimeters, measure of angle B = 36 degrees and measure of angle C = 75 degrees , what is the len

The length of side b is 7.61 m.

Here's how the length was calculated:

Let:

length of side a = 12 centimeters
B = 36 degrees
C = 75 degrees

In order to solve an AAS triangle, use the three angles, add to 180 degrees to find the other angle, then, use The Law of Sines to find each of the other two sides.

A = 180 - (36 + 75) = 69 degrees

by using the law of sines:

a / sin A = b / sin B = c/ sin C

we will substitute the given values:

12 / sin (69) = b / sin (36)

b = unknown

12 / 0.93 = b / 0.59

12.9 = b / 0.59

b = 12.9 * 0.59

b =7.61 cm (length of side b)

Graph the equation by plotting three points. If all three are correct the line will appear -3y=-2x-6
Pachacha [2.7K]
Three possible points are:
(-3, 0)
(0, 2)
(3, 4)

To find any points, simply select any value for x. Input that value, then find the corresponding y-value.

For example, if x = 0, then:

-3y = -2(0) - 6
-3y = -6
y = 2

Which system of equations can be used to find the roots of the equation4x^5-12x^4+6x=5x^3-2x?
goblinko [34]

Answer:

y = 4x^5 - 12x^4 + 6x and

y = 5x^3 - 2x

Step-by-step explanation:

The system of equations that can be used to find the roots of the equation 4x^5-12x^4+6x=5x^3-2x are;

y = 4x^5 - 12x^4 + 6x and

y = 5x^3 - 2x

We simply formulate two equations by splitting the left and the right hand sides of the given equation.

The next step is to graph these two system of equations on the same graph in order to determine the solution(s) to the given original equation.

The roots of the given equation will be given by the points where these two equations will intersect.

The graph of these two equations is as shown in the attachment below;

The roots are thus;

x = 0 and x = 0.813

Answer:

2x³ + 11x² + 8x - 16

Step-by-step explanation:

Multiply:

(x + 4) (2x² +3x - 4)

2x³ + 3x² - 4x + 8x² + 12x - 16

Combine like terms:

2x³ + 11x² + 8x - 16
