An airplane climbs at an angle of 12° with the ground. Find the horizontal distance it has traveled once it has reached an altitude of 500 feet. using cos
Answer:
2352.32
Step-by-step explanation:
Sin 12 = 500/H
H = 2404.86717
Cos(12) = A/2404.86717
A = 2352.32
The horizontal distance it has traveled once it has reached an altitude of 500 feet is approximately 2352 feet.
The situation forms a right angle triangle
What is a right angle triangle?A right angle triangle has one of its angles as 90 degrees. The sides and angles can be found using trigonometric ratios.
The altitude of the plane is the opposite side.
The horizontal distance it travelled is the adjacent side of the triangle formed.
Therefore,
tan 12 = opposite / adjacent
tan 12 = 500 / a
a = 500 / tan 12
a = 500 / 0.2125565616
a = 2352.31573723
a = 2352 feet

I did a test on this i got it correct
Answer:
4. metres (approx)
Step-by-step explanation:
The given situation can be illustrated as a picture which I have attached to the answer for better understanding.
As you can notice, the situation can be modeled as a right triangle.
Use the Pythagorean theorem to find the value of leg h, as follow:
[tex]h=\sqrt[]{(7.5m)^{2} - (6.2m)^{2}} \\h=\sqrt{56.25m^{2} - 38.44m^{2}}\\h=\sqrt{17.81m^{2} } \\h= 4.2 m[/tex]
Rounding of the answer : 4 meters
Hence, the height of the tree is approximately 4m.

Answer:
x = 37
Step-by-step explanation:
2x and 74 are vertically opposite angles and are congruent, so
2x = 74 ( divide both sides by 2 )
x = 37
Step-by-step explanation:
To find the value of x, first, the denominators are made equal by taking the L.C.M. of them.
(3x + 2)/7 + (4(x + 1))/5 = 2/3 * (2x + 1) (45x + 30 + 84x + 84)/105 = (140x + 70)/105
Since both the sides of the equation have the same denominator now, they can be cancelled out.
45x + 30 + 84x + 84 = 140x + 70
The equation can be rearranged by shifting all the x terms on one side of the equation and all the constants on the other side of the equation.
140x - 85x - 45x = 84 + 30 - 70
10x = 44
x = 4.4
Therefore, the value of x is 4.4.
i really need help please give a simple and plain answer like the exaple in the photo
Answer:
Hi! To find x (the missing angles of the triangles), remember that the angles in a triangle add up to 180 degrees. This means that for each triangle, you can add the two angles given, then subtract that number from 180 to find x. I'll use Triangle 1 as an example:
81 + 84 = 165
180 - 165 = 15
So for Triangle 1, x is equal to 15.
To classify each triangle by angles, remember that an acute triangle has three angles that each measure less than 90 degrees, a right triangle is a triangle with one 90 degree angle, and an obtuse triangle is a triangle with one angle that is greater than 90 degrees. To classify each triangle by sides, remember that scalene triangles have three sides of unequal length, isosceles triangles have two sides of equal length, and equilateral triangles have three sides of equal length.
Keeping all this in mind, here are your answers:
Triangle 1 - 15 acute scalene
Triangle 2 - 120 obtuse scalene
Triangle 3 - 41 right scalene
Triangle 4 - 104 obtuse isosceles
Triangle 5 - 25 right scalene
Triangle 6 - 64 acute scalene
Triangle 7 - 72 acute scalene
Triangle 8 - 32 obtuse scalene
Triangle 9 - 40 right scalene

Answer:

Step-by-step explanation:
Start by finding the measure of the angle adjacent to the one marked 101 degrees. Since they are a linear pair, they add up to 180 therefore...
101+y=180
Subtract 101 from both sides...
y=79
Now, using the exterior angle theorem (the exterior angle is equivalent to the sum of the two interior angles that are NOT adjacent to the exterior angle), we can set up an equation to find x...

Answer:
x = 109°Step-by-step explanation:
(x° - 38°) + x + 90° + 90° = 360°
(The sum of the interior angles of any quadrilateral is 360°)
[tex](x - 38) + x + 90 + 90 = 360 \\ x - 38+ x + 180 = 360 \\ x + x + 180 - 38 = 360 \\ 2x + 142 = 360 \\ 2x = 360 - 142 \\ 2x = 218 \\ \frac{2x}{2} = \frac{218}{2} \\ x = 109 \\ [/tex]
The total angle measures a quadrilateral has is 360 degrees and in the problem, we are told that two of the angles are both 90 degrees. So thats 180 degrees out of the way and now we have x+(x-38)=180 which is 2x-38=180 then you add 38 to both sides to get rid of the 38 on the left side and then you end up with 2x=218 so you have to divide both sides by 2 to remove the 2 from x and you would get x=109

Anita went to lunch with some friends and paid $260 for the final bill, including tip. If they left a 16% tip, what was the bill before the tip?
Answer:
The bill was $218.40 before the tip
Step-by-step explanation:
The $260 is the amount with the tip, if 16% of the bill was the tip, we need to find what 100% - 16% of the bill is.
[] First, 100% - 16% is 84%
-> We need to find 84% of $260
[] Next, 84% can become 0.84
-> 260 * 0.84 = $218.40
