Answer:

62.73° or 1.09 radians

Step-by-step explanation:

SOH CAH TOA

sin = \frac{opposite}{hypotenuse}, so sin (?) = \frac{8}{9}

this means that ? = sin^{-1}(\frac{8}{9}) or ? = arcsin(\frac{8}{9}), depending on what calculator you have

plugging in sin^{-1}(\frac{8}{9}) or arcsin(\frac{8}{9}) into calculator will get you

62.73° or 1.09 radians

use the corresponding answer depending on if the question asks for degrees or radians

If 20 coins are tossed, find the probability that they'll all land on tails.
marishachu [46]
The probability would be split for this problem cause knowing with 20 coins , you can split that even amount ... here's what I would do..


Michelle has 20 coins , but only half of them land on heads and others on tails


As for a half , halves are always equaling to 1/2 or 50 (%)  knowing we have 20 , you can evenly split that number of coins in a equal position

So ask your self .. what is half of 20? hmmm .. oh I got it , its 10! so knowing you have 20 but then later you split into half which is 10 ... meaning and knowing you have a 50% probability of getting the 20 coins hitting onto tails

hope this helps!

Meg constructed triangle POQ and then used a compass and straightedge to accurately construct line segment OS, as shown in the f
jarptica [38.1K]
In order to understand this question, one needs to understand the construction first. After creating POQ, Meg picks a radius r and makes a circle around O. There are 2 points where the circle meets the triangle. Then, she meets another radius and she makes a circle of radius s around each of the points on the triangle. The two circles cross at one point, as can be seen in the figure. Let's name the first two points A and B and let's name the last point S. We have that for the triangles OAS, OBS we have OA=OB=r, BS=AS=s and that OS is common to both. Thus by the S-S-S triangle equality theorem, the triangles are equal. Hence for the angles AOS=BOS, namely POS=QOS. Since POQ=POS+QOS, we have that POS has to be half of POQ. The only consistent choice is the third one, POS=20 degrees and POQ=40 degrees.

<u>Answer:</u>

  • The value of x is 14.

<u>Step-by-step explanation:</u>

<u>We know that:</u>

  • ΔABC ≅ ΔEFG
  • 21 x 2/3 = x

<u>Work:</u>

  • 21 x 2/3 = x
  • => 7 x 3 x 2/3 = x
  • => 7 x 2 = x
  • => 14 = x

Hence, <u>the value of x is 14.</u>

Hoped this helped.

The length of a rectangular park is 3 feet shorter than times its width. If the length is 123 feet, what is the width of the par
VLD [36.1K]

Answer:

Width is 120ft but may be different if the "times the width" information is given. Follow the same process.

Step-by-step explanation:

To solve the problem, write an expression that relates length and width using the information given to you. "The length of a rectangular park is 3 feet shorter than times its width" means that l = 3 + w. Since no number is given for "times its width" we disregard this portion. If you have the information then you would include it here l = 3 + _w.

So using the expression l = 3 + w, substitute l = 123. Then the width will be:

l = 3 + w

123 = 3 + w

120 = w
