Actually Welcome to the concept of trigonometry.

Here, we use the Sine ratio.

Sine 60° = 21/x

===> since sin60° = √3/2

==> x = 21*2/√3

==> x = 42/√3

rationalizing we get as,

==> 42√3/3 ===> 14√3

hence, x = 14√3 units,

so finally, x = 14√3 , option C.) is correct.

The height, in inches, of each of three boys is 54.0, 48.5, and 46.0, respectively. The height of the fourth boy is denoted by h

Bingel [31]

Answer:

53.5

Step-by-step explanation:

c = the height of the first 3 boys.

c = 54 + 48.5 + 46

c = 148.5

Now you add a fourth boy. His height is h.

A(h)= (c + h)/d

d = the total number of boys which is 4.

The new average is 50.5

A = (c + h)/d

50.5 = (148.5 + h) / 4 Multiply both sides by 4

202 = 148.5 + h Now subtract 148.5 from both sides

202 - 148.5 = h

h = 53.5

As shown in the image below, triangle ABC is reflected onto its image. А B с С" A Which of the following lines represents the li

dybincka [34]

Answer:

Line of reflection will be y = -2

Step-by-step explanation:

From the picture attached,

Triangle ABC has been reflected over an unknown line so that the triangle ABC will overlap triangle A'B'C'.

To find the line of reflection,

Coordinates of point C → (7, 0)

Coordinates of point C' → (7, -4)

Line of reflection = line passing through midpoint of the line joining C and C'

Midpoint of the line joining points C and C' = $(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

= $(\frac{7+7}{2},\frac{0-4}{2})$

= (7, -2)

Therefore, line of reflection is y = -2.

Help 15 pts just for you!!!: A function f(x) is graphed on the coordinate plane. What is the equation of this line?

Rufina [12.5K]

The y-intercept (b) can be found instantly from the graph: (0,-2).

The slope is

0 - (-2)
m = ----------- = 2/6 = 1/3
6 - 0

Thus, using y = mx + b, we find that the equation of this line is y = (1/3)x - 2.
