What is the length of line RS? Use the law of sines to find the answer.Round to the nearest tenth.
vitfil [10]
Refer to the diagram below.

Let x = length of line segment RS.
Let Q = ∠RQS.
Let S = ∠RSQ

According to the Law of Sines,
\frac{sinS}{2.4} = \frac{sin80^{o}}{3.1} \\\\sinS = (\frac{2.4}{3.1}) sin 80^{o}= 0.7624 \\\\ S = sin^{-1}0.7624 = 49.68^{o}

Because the sum of angles in a triangle is 180°, therefore
∠Q = 180 -(80 + 49.68) = 50.32°

Apply the Law of Sines again to obtain
\frac{x}{sinQ} = \frac{3.1}{sin80^{o}} \\\\ x = ( \frac{sin50.32^{o}}{sin80^{o}})3.1 =  2.423

Answer: The length of RS = 2.4 (nearest tenth)

Classify the four angles of the quadrilateral. B 105° A .90° 75° C 90° D LA LB 4C ZD Right Acute Obtuse O X O O Ś ?
earnstyle [38]

The picture has a quadrilateral with ABCD angles.

∠A=90° is right angle

∠B=105° is obtuse angle

∠C=75° is acute angle

∠D=90° is right angle

Given that,

The picture has a quadrilateral with ABCD angles.

The angle are

∠A=90°

∠B=105°

∠C=75°

∠D=90°

We have to clarify the angles of the quadrilateral.

∠A is right angle because the right angle is created when two straight lines cross at a 90° angle or when they are perpendicular at the intersection.

∠B is obtuse angle because a form of angle known as an obtuse angle is one that is always greater than 90° but less than 180°.

∠C is acute angle because an acute angle is one that is smaller than 90 degrees in length. L-shape shapes at 90°

∠D is right angle because the right angle is created when two straight lines cross at a 90° angle or when they are perpendicular at the intersection.

What pattern can i say here 2,5,11,23,47
Vilka [71]

Answer:

Your rule is: Multiply 2, Add 1

Step-by-step explanation:

Check:

2 x 2 = 4 + 1 = 5

5 x 2 = 10 + 1 = 11

11 x 2 = 22 + 1 = 23

23 x 2 = 46 + 1 = 47

What are the coordinates of the image of vertex D after a reflection across the x-axis?
Elena-2011 [213]

Answer:

(-3,5) ia the answer

Step-by-step explanation:

It is because when you reflect it across the x axis the first coordinate will be negative and the second number is positive since its in the second square of the graph, so it is more of a resonable guess.
