Answer:
x=147°
Step-by-step explanation:
1. Analyze: The angle opposite to the 33 degree angle is 33 degrees because they are vertical angles.
2. Make an equation: The sum of all four angles (x, the angle opposite of x, the 33 degree angle, and the angle opposite of the 33 degree angle) is 360°. Therefore the equation would be (33°x2)+2x= 360°.
3. Solve for x:
a. Multiply 33 by 2
66+2x=360
b. Subtract 66 from both sides
66+2x=360
-66 -66
2x=294
c. Divide both sides by 2
[tex]\frac{2x}{2} =\frac{294}{2}[/tex]
x=147
4. Remember to add your label- the degree sign (°)
x=147°

Answer:
3( -8 + 1) = 3( -8) + 3(1)
Step-by-step explanation:
That is distributive property
Answer:
3(-8+1)=(3(-8)+(3(1)
Step-by-step explanation:
In this case, distributive property is when a number or you could call it integer, multiplies with another set of number inside parentheses ().
Your answer was wrong, because 6 x 7=42, and that's not equal to the other side of numbers.
The top one is addition, so that's a no.
The second one's not exactly in the form you want it to be for it to be the same as the left side.
The third one shows distributive property in two ways, which give you the same result, so that would be the correct answer.
Hope this helped!

Which triangle can be used to find the slope of the line shown? explain your answer
Answers
Answer:
A right triangle contains a right angle, so it must have two sides that are perpendicular. If the slopes of two sides can be shown to be negative reciprocals of each other, then it can be concluded that a right angle is formed. If a triangle contains a right angle, then it is a right triangle
Step-by-step explanation:
to determine if a triangle is a right triangle using slopes, you have to understand perpendicular slopes/negative reciprocals.
You can calculate the slope of all 3 sides of the triangle and if two of the slopes are negative reciprocals, then those two lines intersect creating a right angle/right triangle.
Let's say there's triangle ABC.
If the slope of AB is 1/2
and the slope of BC is 2/5
and the slope of CA is -2/1
then AB and CA intersect resulting in a right angle (triangle).

Answers
Answer:
m<B = 93°
Step-by-step explanation:
Based on the inscribed quadrilateral theorem, the opposite angles of a cyclic quadrilateral are supplementary.
Thus:
m<B + m<D = 180°
Substitute
m<B + 87° = 180°
m<B = 180° - 87°
m<B = 93°

a) The average rainfall of the last week was 35 mm. If the records of daily
rainfall from Sunday to Friday were 45 mm, 22 mm, 28 mm, 36 mm, 30 mm
and 24 mm, find the rainfall on Saturday.
Answers
Answer:
The rainfall on Saturday was of 60 mm.
Step-by-step explanation:
Average rainfall:
The average rainfall is given by the total rainfall divided by the number of days(7). So
If the records of daily rainfall from Sunday to Friday were 45 mm, 22 mm, 28 mm, 36 mm, 30 mm and 24 mm
On Saturday it was of x mm. So
[tex]35 = \frac{45 + 22 + 28 + 36 + 30 + 24 + x}{7}[/tex]
[tex]185 + x = 245[/tex]
[tex]x = 245 - 185[/tex]
[tex]x = 60[/tex]
The rainfall on Saturday was of 60 mm.

Answer:
diameter = 2.5 feet
Step-by-step explanation:
Circumference of a circle is given as C = πd
Circumference of the tree trunk = 7.85 ft
π = 3.14
Diameter of the tree trunk = d
Thus:
7.85 = 3.14*d
Divide both sides by 3.14
7.85/3.14 = 3.14*d/3.14
2.5 = d
d = 2.5 ft
A researcher reports that the standard deviation in population is A is q= 2.3 and the standard deviation in population B is q=4.3. Which population is associated with the highest power to detect an effect?
Answers
Answer:
Population A
Step-by-step explanation:
Usually in statistics, the more we increase the sample size, the more the standard deviation decreases. Similarly, the more we decrease the sample size, the more the standard deviation increases.
Finally, the more the standard deviation or error of Variance the lesser the power to detect an effect.
In this question, Population B has a greater standard deviation and thus would not have as much power as Population A in detecting an effect.
Thus Population A with standard deviation of 2.3 will have highest power to detect an effect.

In the image you can see that a side length divided by sin(its opposite angle) is equal to another side length divided by sin(its opposite angle)
so to find x we use this equation
[tex]\frac{x}{sin59} =\frac{17}{sin90}[/tex]
step 1 multiply each side by sin 59
now we have
[tex]x=\frac{17sin59}{sin90}\\x = 14.6[/tex]
so we can conclude that x = 14.6
