Answer:
y = 122
Step-by-step explanation:
let us start by adding some angles ourselves.
we are going to add angles at the right side of 150 and at the left of y
we can call the angle beside 151 x and the angle beside y A
first of all, let us find the value of x
now, angles 151 and x add up to 180 because angles on a straight line add up to 180 and the two angle are on a straight line of their own
which means;
151 + x = 180
when we collect like terms,
x = 180 - 151
x = 29
therefore, our x = 29
next, we find A
now, angles 29 ( our x ), 93 and our A all add up to 180 because the sum of angles in a triangle is 180 and our angles are in a triangle ( at least an upside down one with lines shooting out from every end )
that is;
29 + 93 + A = 180
collect like terms
A = 180 - 29 - 93
A = 180 - 122
A = 58
so, now that we have our angle A, the next thing to do is the same thing we did to get angle x,
we can see that A and y are both on a straight line of their own which means that they both add up to 180 degrees
that is;
A + y = 180
and we know that A = 58
so;
58 + y = 180
we collect like terms to have
y = 180 - 58
y = 122
therefore, y = 122
if you might have noticed, y is the same as x and 93
and that is correct because according to a rule in math, the value of an exterior angle of a triangle is equal to the sum of its opposite interior angles of the triangle. this can be explained using our question above

a submarine is located 358 feet below sea level. it ascends 169 feet. At what depth is the submarine now
Answers
Answer:
189
Step-by-step explanation:
Ascending means to go upwards. So, since it is below the surface heading upwards, you would subtract the amount of feet that it went up by from the depth it was previously at.
358, take away 169, is 189.

-8cot square A + 8 cosec square A
Answers
Answer:
8
Step-by-step explanation:
Using the identity
cosec²A = 1 + cot²A
- 8cot²A + 8cosec²A
= - 8cot²A + 8(1 + cot²A)
= - 8cot²A + 8 + 8cot²A
= 8

Let (x1, y1) = (10, 30)
(x2, y2) = (50, 50)
Use the following slope formula:
m = (y2 - y1)/(x2 - x1)
m = (50 - 30) / (50 - 10)
m = 20/40 or 1/2
Therefore, the slope of the line is 1/2.

Write the equation of the line in fully simplified slope intercept form
Answers
Answer:
y = -x - 8
Step-by-step explanation:
I don't know what it means by "fully symplified", but this is how I would answer.
Hope this helps, and if not, I'm sorry!
Answer:
[tex]y=-x-8[/tex]
Step-by-step explanation:
Slope intercept form is in the general form
[tex]y=mx+b[/tex] such that [tex]m[/tex] is the slope of the line, and that [tex]b[/tex] is the y-intercept of that line.
The equation for slope can be denoted as any of those below
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex] Where the y and x terms are from two ordered pairs
[tex]m=\frac{rise}{run}[/tex], such that rise is the vertical change in a line, and run the run is the horizontal change
Work!
In this case, since we are given nothing but a line, we should use [tex]m=\frac{rise}{run}[/tex]
Since the graph goes down by 1 for every 1 distance to the right, the change in rise of y (-1) divided by the run of x (1) means that [tex]m=-1[/tex]
We now have [tex]y=-x+b[/tex]
Since b is the y-intercept, according to the graph [tex]b=-8[/tex]
This leaves you with the final answer of [tex]y=-x-8[/tex]
Hope this helps! :)

θ = sin inverse - 0.9419
= sin^-1 ( - 0.9419 )

Mr James gives £500 to his children Ally,
Barry and Cat in the ratio 2:3:5.
How much do they each receive?
Answers
Answers:
Ally gets 100 poundsBarry gets 150 poundsCat gets 250 pounds=====================================================
Work Shown:
x = some positive real number
2x = amount Ally gets
3x = amount Barry gets
5x = amount Cat gets
Note that the ratio 2x:3x:5x reduces to 2:3:5 after dividing all parts by x.
Add up the parts and you should get a sum of 500 pounds. Solve for x.
2x+3x+5x = 500
10x = 500
x = 500/10
x = 50
Based on that x value, we then can say:
2x = 2*50 = 100 pounds is what Ally gets3x = 3*50 = 150 pounds is what Barry gets5x = 5*50 = 250 pounds is what Cat getsAs a check, 100+150+250 = 500.
Also, note that the ratio 100:150:250 fully reduces to 2:3:5 after dividing all parts by the GCF 50.
Those two facts help confirm our answers.
