In a right triangle the hypotenuse which is 16+9 =25 has to be the largest side. Since x is not the hyportenuse it has to be lower which only leaves one answer : 15
Answer:
Step-by-step explanation:
these are tough to solve , don't feel bad. soo part of the trick is that the two side set up similar triangles, then
16 / y = y /9 ( the two triangles
16* 9 = [tex]y^{2}[/tex]
144 = [tex]y^{2}[/tex]
12 = y
y is the length between the two triangles , so since we now know that part, we can solve the triangles.
lets use tan to solve one of the angles of the smaller triangle
TOA to remember how tan fits on a triangle
Tan = Opp / Adj
Tan(Ф) = 9/12
Ф = arcTan(9/12)
Ф = 36.869897
knowing that we can solve for x
use CAH cos = Adj / Hyp
Cos(36.869897) = 12 / Hyp
Hyp = 12/ Cos(36.869897)
Hyp = 15 :) that seems reallly good .. :P
x = 15 there you go

Given that R=7x+5Y find Y when X=9 and R=35 give your answer as an improper fraction in its simplest form
Please help
Answers
Answer:
y = -28/5
Step-by-step explanation:
R = 7x +5y
35 = 7(9) + 5y
35 = 63 +5y
-5y= 63- 35
-5y/-5 = 28/-5
Y = -28/5
Answer:
Y = - [tex]\frac{28}{5}[/tex]
Step-by-step explanation:
Given
R = 7X + 5Y ← substitute X = 9, R = 35
35 = 7(9) + 5Y
35 = 63 + 5Y ( subtract 63 from both sides )
- 28 = 5Y ( divide both sides by 5 )
- [tex]\frac{28}{5}[/tex] = Y

The graph shows a line and two similar triangles. What is the equation of the line
Answers
Answer:
y = (1/3)x + 2
Step-by-step explanation:
The equation of a straight line is given by:
y = mx + b, where y and x are variables, m is the slope of the line, that is the ratio of the change in vertical distance to horizontal distance while b is the y intercept of the graph.
From the graph, we can see that the y intercept (where the graph touches the y axis) is 2. Hence b = 2
Also, the slope (m) = change in y / change in x = 1 / 3
The equation of the line is:
y = (1/3)x + 2
Answer:y = (1/3)x + 2

Answer:
43.94?
Step-by-step explanation:
I think if you use inverse cos you should get the correct number. So, to find cos, you need to know the adjacent side and the hypotenuse. Here, the reference angle would be the person holding the kite. The distance from the person to the barn is the adjacent side, which is 18. The string of the kite, I assume, would be 25.
cos(∅) = [tex]\frac{18}{25}[/tex]
cos(∅) = 0.72
cos⁻¹(0.72) = 43.94
I don't know if that's what you're looking for, but... If it's not correct, lmk so I can rewrite it. :)

The sum of three consecutive even numbers is 132. What are those three numbers? Explain how you found your answer.
Answers
Answer:
43, 44 and 45
Step-by-step explanation:
As it is mentioned consecutive, we can take the numbers as
x, x + 1 and x + 2
so x + (x + 1) + (x + 2) = 132
3x + 3 = 132
3x = 129
x = 43
Other two number are:
x + 1 = 44
x + 2 = 45
The numbers are 43, 44 and 45.
3x+6=132
X=132-6/3
X=42
42,42+2,42+4
42,44,46

We need to simplify the given expression i.e.
3x+4y+7y
We know that, the like terms gets add up i.e. the sum of 4y and 7y equals 11 y
So,
3x+4y+7y = 3x + 11 y
Hence, the final simplification should be 3x + 11 y.
