Use an inverse trig function to find the missing angle measure. Round your answer to the nearest tenth (first decimal place)​

Answers

Answer:

  x° ≈ 51.1°

Step-by-step explanation:

In this geometry, you are given the side opposite the angle, along with the hypotenuse. The relevant trig relation is ...

  Sin = Opposite/Hypotenuse

  sin(x°) = 14/18

  x° = arcsin(14/18) ≈ 51.0576°

  x° ≈ 51.1°

Answers

Answer:

B or 50%

Step-by-step explanation:

First, you add all of them together

30 + 16 + 14 = 60

Then you do the part/whole

30/60 = 1/2

1/2 = 50%

what are the lengths of sides a and c ​

Answers

Answer: a is 4 mm, c is 8 mm

Step-by-step explanation:

the 30-60-90 triangle rule: in a right triangle with 30, 60 and 90 degree angles, the adjacent side  is [tex]\sqrt{3}[/tex] the opposite side, while the hypotenuse is 2 times the opposite.

the adjacent side in this case would be 4[tex]\sqrt{3}[/tex], a is opposite, and c is the hypotenuse

divide the adjacent side by [tex]\sqrt{3}[/tex]  and we have the opposite side: 4

the hypotenuse is twice the opposite side, which has a value of 4. 4 times 2 is 8, which means the value of the hypotenuse is 8 mm

Answer:

true, true, false

Step-by-step explanation:

the sales do not decrease between week 4 and 5

Answer:

The answer is True, True, False

Step-by-step explanation:

For the first one, it is true because if you look on the graph, on the bottom or the x-axis, it is labeled "weeks". If you pay attention to when the line on the graph is, you will se that it is a straight line through weeks 1 and 2, so number one is true.

For the second one, it is also true because on the graph, you can see the the line starts to go upwards or increase. While the line is doing that, you can look right under it and see that it is passing through weeks 3 and 4, so that is True.

For the last one, it is false because on the graph, the line keeps going upwards for weeks 5 and 6, and the statement says that it is decreasing or going down, which is incorrect, so finally, the last question is false.

Hope this helps!

Find the area of a sector, whose perimeter is 40 cm, and the radius is 8 cm.

Answers

Answer:

96 cm²

Step-by-step explanation:

From the question,

s = (2πr∅/360)+2r................. Equation 1

Where s = Perimeter of a sector, r = radius, ∅ = angle subtend by the sector at the center of the circle.

Given: s = 40 cm, r = 8 cm

Constant : π = 3.14.

Substitute into equation 1 and solve for ∅

40 = (2×8×3.14×∅/360)+(2×8)

40 = (50.24∅/360)+16

40-16 = 50.24∅/360

50.24∅/360 = 24

50.24∅ = 24×360

50.24∅ = 8640

∅ = 8640/50.24

∅ = 171.97°

Area of a sector (A') = ∅πr²/360

A' = 171.97×3.14×8²/360

A' = 95.997

A' ≈ 96 cm²

D 1/3

Answers

Answer:

B) 1/5

Step-by-step explanation:

Remy has 2 taxis, and 10 cars in all. It is asking for the probability that Remy will choose a taxi. Divide the amount of taxis from the total amount of cars. Simplify the fraction:

2/10 = (2/10)/(2/2) = 1/5

B) 1/5 is your answer.

Please help.. I really don't understand this

Answers

Answer:

The answer is 62 degrees

Step-by-step explanation:

I was kind of anticipating this question, given the others you posted. :) It builds on what you learned in the last 2.

Two angles that form a straight line = 180 degrees.

So x + 149 = 180, x = 31.

Now look at the horizontal line that is parallel on top. The corresponding angle for x is the upper left angle.

And the prior example also said that vertical angles/opposite angles are equal. So x = y, so y = 31 also.

The question is what is x + y

31 + 31 = 62

please let me know if you have questions about this.
