Answer:
[tex]\angle\,JLF = 114^o[/tex] which agrees with option"B" of the possible answers listed
Step-by-step explanation:
Notice that in order to solve this problem (find angle JLF) , we need to find the value of the angle defined by JLG and subtract it from [tex]180^o[/tex], since they are supplementary angles. So we focus on such, and start by drawing the radii that connects the center of the circle (point "O") to points G and H, in order to observe the central angles that are given to us as [tex]90^o[/tex] and [tex]138^o[/tex]. (see attached image)
We put our efforts into solving the right angle triangle denoted with green borders.
Notice as well, that the triangle JOH that is formed with the two radii and the segment that joins point J to point G, is an isosceles triangle, and therefore the two angles opposite to these equal radius sides, must be equal. We see that angle JOH can be calculated by : [tex]360^o-90^o-138^o=132^o[/tex]
Therefore, the two equal acute angles in the triangle JOH should add to:
[tex]180^o-132^o=48^o[/tex] resulting then in each small acute angle of measure [tex]24^o[/tex].
Now referring to the green sided right angle triangle we can find find angle JLG, using: [tex]180^o-24^o-90^o=66^o[/tex]
Finally, the requested measure of angle JLF is obtained via: [tex]180^o-66^o=114^o[/tex]

Step-by-step explanation:
Use the formula for the perimeter of a rectangle.
[tex]P=2l+2w[/tex]
[tex]180=2l+2(30)[/tex]
[tex]180=2l+60[/tex]
[tex]180-60=2l[/tex]
[tex]120=2l[/tex]
[tex]\frac{2l}{2}=\frac{120}{2}[/tex]

Data Set B: 18, 19, 21, 25, 29,32
Median:
Data Set A = 26
24 + 28 = 52
52/2 = 26
Data Set B = 23
21 + 25 = 46
46/2 = 23
Mean:

Answer:
positive
Step-by-step explanation:
the line is tilting up (you read it from left to right)
The slope of the line is, O positive.
What is slope?In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
here, we have,
from the given graph,
we get,
the straight line is in the positive direction.
Hence, The slope of the line is, O positive.

Find x in the following right triangle.
Answers
Answer: 15
Step-by-step explanation: I used the pythagorean theorem. X is a, 8 is b, and 17 is c. The squares of a and b added together are c. So I got 15.
Answer:
x=15
Step-by-step explanation:
First, you are going to find a Pythagorean Triple. As you can see from the picture you have provided, 17 ft is the longest side. So, I squared 17 and got 289. I did this because I am using the Pythagorean Theorem (a^2+b^2=c^2). Then, I squared 8 and got 64. Then, still following the Pythagorean Theorem, I subtracted 64 from 289. I got 225. Then, I found the square root of 225. I got 15. So, x=15.

Answers
You have (-3 +i)/(7 + i) so you need to remove the i from the numerator, so you have to multiply by 7-i and you get
(-22 + 4i)/50 which can be simplified to
(-11 + 2i)/25
Answer:
Step-by-step explanation:
What you are trying to do in this question is get rid of the i in the denominator. To do that you must multiply top and bottom by the conjugate of 7 + i
The conjugate is 7 - i
D if correct if you just made a typo. Otherwise there is no answer.
( - 3 + i ) * (7 - i)
=============
(7 + i ) ( 7 - i)
( - 3 + i ) * (7 - i)

=============
49 + 1

I'll let you work out the numerator. If you get (-2 + i)/5 you are correct.

solve the formula for calculating the perimeter of a parallelogram with sides b and c for c p = 2b+2c
Answers
Answer:
Proved;
See Explanation
Step-by-step explanation:
Given:
Shape: Parallelogram
Sides: b and c
Required:
Show that P = 2b + 2c
Let P represents the perimeter of the parallelogram.
There are 4 sides in a parallelogram where 2 sides are opposite and parallel
Given that two of the side of the parallelogram is b and c; this implies that the next two sides are also b and c.
This means that the sides of the parallogram are b,c,b,c
The perimeter of any shape is calculated by adding the lengths of the shape;
This means that
[tex]P = b + c + b + c[/tex]
Collect like terms
[tex]P = b + b + c + c[/tex]
[tex]P = 2b + 2c[/tex] ------ Proved
