Answer:

65°

Step-by-step explanation:

<u>Properties of a triangle:</u>

  • Triangles always have 3 sides
  • <u><em>The sum of the interior angles of a triangle must be equal to 180°.</em></u>

<u>To solve:</u>

  • <u>Since the angles inside of a triangle must always be equal to 180, use the following formula to solve:</u>
  • <em>a</em> + <em>b</em> +<em> c</em> = 180
  • (The variables can be assigned to any value in this situation)
  • <u>Since two angles are already given, replace 2 variables:</u>
  • <em>a</em> + 85 + 30 = 180
  • <u>Solve the equation by subtracting on both sides:</u>
  • <em>a</em> = 65
  • The value of <em>a</em> is the measure of the missing angle. The problem is solved.

Answer:

the missing angle is 65

Step-by-step explanation:

a whole triangle is 180

subtract the given angles from 180

<em>   180</em>

<em>-   85</em>

<em>----------</em>

<em>    95</em>

subtract the remaining angle

<em>   95</em>

<em>-  30</em>

<em>---------</em>

<em>   65</em>

A baker knows that the daily demand for strawberry pies is a random variable that follows the normal distribution with a mean of
Elan Coil [88]

The demand that has an 8% probability of being exceeded is 38.1230 .

<h3>What is probability?</h3>

Probability is the aspect of mathematics that focus on the occurrence of a random event.

This is calculated below:

The  normal random variable having the  mean is been given as :

(Mu = 31.8)

The standard deviation is been given as ( sd = 4.5)

Then in making our calculation, we will need to make use of the formular below:

\\Z= (X - Mu) / sd = (X - 31.8) / 4.5

But we know that going with the  probability of 0.08

where  k = 1.4051

P (Z > 1.4051)

k = 1.4051

we can have the expression for  k  as [(X - 31.8) / 4.5]

This can be simplified as:

X  = 4.5 (1.4051) + 31.8 = 38.1230.

Therefore, the  demand that has an 8% probability of being exceeded is 38.1230 .

What is the value of x? A.86 B.60 C.52 D.26
Nadya [2.5K]

   First of all in order for us to figure out what angle x is we need to find the formula for finding that specific type of angle.

Formula is...

x = (far arc - close arc) ÷ 2

Now we just need to plug in.

x = (172° - 52°) ÷ 2 =

x = 120° ÷ 2 = 60°

Your answer: x = 60°

Good Luck! :)

Secant jkl and jmn are drawn to circle o from an external point ,j. if jk=8,lk=4 and jm=6 what is the length of jn answer
Archy [21]
See the picture attached to better understand the problem

we know that
If two secant segments are drawn to a <span>circle </span><span>from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment.
</span>so
jl*jk=jn*jm------> jn=jl*jk/jm

we have
<span>jk=8,lk=4 and jm=6
</span>jl=8+4----> 12

jn=jl*jk/jm-----> jn=12*8/6----> jn=16

the answer is
jn=16
