What are trigonometric relations?
Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the angle be represented as A
Now , the value of A is
A = arc cos ( 0.21 )
The value of arc cos ( 0.21 ) = 1.35922137 rad
The value of 1 rad = ( 180°/π ) degrees
So , 1.35922137 rad = 1.35922137 ( 180°/π ) degrees
On simplifying the equation , we get
The value of arc cos ( 0.21 ) = 77.8776478 degrees
Rounding to the nearest hundredth , we get
The value of arc cos ( 0.21 ) = 77.88 degrees
Hence , the measure of arc cos ( 0.21 ) is 77.88°

Find the value of each variable I need 6-10
Answer:
6) 9x-25+9x-25(sum of base angles)
9x-25+9x-25+104=180(sum of angles in a triangle)
collect like terms
9x+9x-25-25+104=180
18x-50+104=180
18x+54=180
18x=180-54
18x=126
divide both sides by 18
18x÷18=126÷18

Write down the equation of a line whose slope is -7 and crosses the y-axis at 7. Express in slope-intercept form.
Answer:
y= -7x+7
Step-by-step explanation:
y= mx+b
y= slope x+ y intercept
The equation of the line having the slope -7 and y-intercept is 7 is: y = -7x + 7
What is the equation of line?A straight line's equation is a relationship between its x and y coordinates, and it is written as y = mx + c, where m is the line's slope and c is its y-intercept.
We are given that the slope m is -7,
and the line crosses the y-axis at 7.
so the value of c = 7
Therefore, we can substitute these values into the slope-intercept form to get:
y = -7x + 7
So the equation of the line is y = -7x + 7.

A sequence is defined by the recusive function fin + 1) = fn). Iff3) = 9, what is f(1) ?
- 1
- 3
- 27
- 81
Answer: 9 is the answer
Step-by-step explanation:
“ Since f(n+1) = f(n)
If n= 1
f(2) = f(1)
if n= 2
f(3) = f(2) = 9 {since f(3) is 9}
Since f(2) is now 9 and f(2) = f(1), therefore f(1) will also be 9.

Answer: The y intercept is 1.
Step-by-step explanation: Sorry I could only answer the one about the y-intercept. So basically finding the y intercept is where the line crosses at the y-axis. So in this case the y-intercept is 1 because thats the point the line crosses at the y-axis. I hope this clarifies your question and I hope this helps.

Carl is making accessories for the soccer team. He uses 666.96 inches of fabric on headbands for 39 players and 3 coaches. He also uses 333.06 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Answer:
The amount of fabric was used on :
a) headband for each player = 15.88 inches of fabric
b) wristband for each player = 8.54 inches of fabric
Step-by-step explanation:
From the above question, we were told:
For headbands
Carl is making accessories for the soccer team. He uses 666.96 inches of fabric on headbands for 39 players and 3 coaches.
Total number of persons = 39 players + 3 coaches = 42 persons
42 persons = 666.96 inches
1 person = x
Cross Y
42x = 666.96 inches
x = 666.96 inches/42
x = 15.88 inches
For wristbands
He also uses 333.06 inches of fabric on wristbands for just the players.
We have 39 players
Hence:
39 players = 333.06 inches
1 players = x
Cross Multiply
39x = 1 × 333.06 inches
x = 333.06 inches/3
x = 8.54 inches
The amount of fabric was used on :
a) headband for each player = 15.88 inches of fabric
b) wristband for each player = 8.54 inches of fabric
