Here are some solutions: (there are actually an infinite amount of them)
x = 0 , y = 7
x = 1 , y = 8
x = 2 , y = 9
x = 3 , y = 10
x = 4 , y = 11
x = 42 , y = 49
x = pi , y = pi + 7
Answer:
Trigonometry can be used to measure the height of a building or mountains
Step-by-step explanation:
if you know the distance from where you observe the building and the angle of elevation you can easily find the height of the building. Similarly, if you have the value of one side and the angle of depression from the top of the building you can find and another side in the triangle, all you need to know is one side and angle of the triangle.
Important:
The sum of the three angles inside
every triangle is always 180°.
First, look at the left triangle alone.
Two of its angles are 46° and 58° . (46° + 58° ) = 104°
That leaves (180° - 104° ) = 76° degrees for the third angle.
The third angle in that triangle is 'x'.
x = 76° .
At the point where 'x' and 'z' come together:
'x' and 'z' are a "linear pair".
Placed side-by-side, they form a straight line.
So (x + z) = 180° .
But x = 76°.
So z = (180° - 76°). z = 104° .
Now look at the the skinny triangle on the right alone.
The angle at the top is 13°, and z = 104°.
(13° + 104°) = 117° .
That leaves (180° - 117°) = 63° for the third angle.
'y' is the third angle.
y = 63° .
Question 7: 40. 40 is way above the other data.
Question 8: Median is 7, and the range is 12, the difference is 5.
Question 9: The first mean was 6, and it went up to 6.75. There is a 0.75 difference.
Question 10: The range increases by one.
