Line segment gj is a diameter of circle l. angle k measures (4x 6)°. circle l is inscribed with triangle g j k. line segment g j
choli [55]

The value of x in the given right triangle in a semicircle is determined as 21.

<h3>What is the measure of a triangle in a semicircle?</h3>

The triangle in a semicircle is always a right angle triangle.

From the figure shown, we can say that the triangle  G J K is right triangle and m<K = 90degrees.

Given that m<K = 4x + 6, we will can use the following equation to find the value of x as shown:

4x + 6 = 90

4x = 90 - 6

4x = 84

x = 21

Thus, the value of x in the given right triangle in a semicircle is determined as 21.

A woman can row a boat at 4.0 mph is still water.
vovikov84 [41]

Answer:

1) \theta=120^{\circ} from the positive x-axis.

2) t=20\ min

Explanation:

Given:

speed of rowing in still water, v=4\ mph

1)

speed of water stream, v_s=2\ mph

we know that the direction of resultant of the two vectors is given by:

tan\ \beta=\frac{v.sin\ \theta}{v_s+v.cos\ \theta}

where:

\beta=the angle of resultant vector from the positive x-axis.

\theta = angle between the given vectors

When the rower wants to reach at the opposite end then:

\beta =90^{\circ}

so,

tan\ 90^{\circ}=\frac{v.sin\ \theta}{v_s+v.cos\ \theta}

\Rightarrow v_s+v.cos\ \theta=0

2+4\times cos\ \theta=0

cos\ \theta=-\frac{1}{2}

\theta=120^{\circ} from the positive x-axis.

2)

Now the resultant velocity of rowing in the stream:

v_r=\sqrt{v^2+v_s^2+2\times v.v_s.cos\ \theta}

v_r=\sqrt{4^2+2^2+2\times 4\times 2\times cos\ 120}

v_r=12\ mph

Therefore time taken to cross a 4 miles wide river:

t=\frac{4}{12}

t=\frac{1}{3}\ hr

t=20\ min

Explain why open pipes are preferred to closed pipe in the production of music-​
tatuchka [14]

Answer:

The frequencies of sounds made by these two types of instruments are different because of the different ways that air will move at a closed or open end of the pipe. Open pipes do not produce superior tone than closed (or stopped) pipes, therefore different types of pipes are used to produce different tonal qualities.
