FIND X ROUND NEAREST 10 PLEASE ILL GIVE BRAINLIEST
Answer:
x=7
Step-by-step explanation:
Hey There!
I believe they want us to use law of sines
To do so we need to find the missing angle
180-90-25=65
now we set up and equation
[tex]\frac{x}{sin25} =\frac{15}{sin65}[/tex]
step 1 multiply each side by sin25
[tex]x=\frac{15sin25}{sin65} \\x=6.994614872[/tex]
it says to round to the nearest tenth so we can conclude that x=7

The graph shows a line and two similar triangles. What is the equation of the line
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. :)

What is the nth term rule of the linear sequence below?
5,8,11,14,17
(btw it says the nth term not the 9th.)
9514 1404 393
Answer:
an = 5 +3(n -1)
Step-by-step explanation:
The n-th term of an arithmetic sequence is ...
an = a1 +d(n -1)
Here, you have first term a1=5 and common difference d=8-5=3, so the n-th term is ...
an = 5 +3(n -1)
_____
If you like, you can simplify this to ...
an = 5 +3n -3
an = 3n +2
Answer:
it's 3n-3

Y=4x+1
Answer:
x=-5/11, y=-9/11. (-5/11, -9/11).
Step-by-step explanation:
3x+2y=-3
y=4x+1
---------------
3x+2(4x+1)=-3
3x+8x+2=-3
11x=-3-2
11x=-5
x=-5/11
y=4(-5/11)+1
y=-20/11+11/11
y=-9/11

Pierre walks 24 km due north then 7 km due east.
Calculate how far he is from his starting position.
Answer:
The answer is 17 km due north.
Step-by-step explanation:
24 km due north subtracted by 7 km east
Put north because it was first (this was based on a rule).
The distance between the final position to the initial position will be 25 km.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
Pierre walks 24 km due north and then 7 km due east. Then the distance between the final position to the initial position will be
H² = 24² + 7²
H² = 576 + 49
H² = 625
H² = 25²
H = 25 km
The distance between the final position to the initial position will be 25 km.
