Step-by-step explanation:
1.
that creates a right-angled triangle :
the string is the Hypotenuse (the baseline, which is the side opposite of the 90° angle).
the invisible "line" from the kite straight down to the ground is one leg. and we need that length.
and the invisible "line" on the ground between the point where Brian is standing, and the point, where the : line: coming down from the kite hits the ground, is the second leg.
the angle between both legs is 90°.
so, we use the law of sine :
a/sin(A) = b/sin(B) = c/sin(C)
where the sides and the associated angles are always opposite of each other.
in our case, the Hypotenuse (the string) is opposite of 90°.
and the angle opposite of the kite height line is the designated angle of elevation at the point, where Brian is standing : 70°.
so, we have here
65/sin(90) = height/sin(70)
height = 65×sin(70)/sin(90)
sin(90) = 1
height = 65×sin(70) = 61.08002035... m
2.
another right-angled triangle.
what is not clear to me : what does "distance from plane to building" mean ?
is it really the line of sight from the plane in the air to the building in the ground ? which is the Hypotenuse of that triangle.
or is it the ground distance (from the point where the height line hits the ground to the building) ? which is also the air distance (parallel line to the ground distance up in the air with the plane).
remember, the sum of all angles in a triangle is always 180°.
per law of sine we have
height/ sin(28) = line of sight / sin(90) =
= air (or ground) distance / sin(180-28-90)
1200/sin(28) = line of sight / 1 =
= air distance / sin(62)
line of sight (if that is what we need) =
= 1200/sin(28) = 2,556.065362... m
air distance = 1200×sin(62)/sin(28) = 2,256.871758... m
3.
another right-angled triangle.
the Hypotenuse is the line of sight from the point 12 ft away in the ground to the top of the pole.
the ground distance (12 ft) is one leg.
the pole (and its height) is the second leg.
so, we have our law of sine
height/sin(53) = line of sight / sin(90) =
= ground distance / sin(180-53-90)
we need the height, so
height/sin(53) = ground distance / sin(37)
height = 12×sin(53)/sin(37) = 15.92453786... ft

Answers
Answer:
4
Step-by-step explanation: You want to divide 94 by 30 and you 3 with a remainder of 4.
Answer: 4 toys
Step-by-step explanation:
We will multiply 3 by 30 for how many toys he can currently put into boxes.
3 * 30 = 90
Now we will subtract this from the total number of toys for our answer.
94 - 90 = 4
There are 4 toys left.

Find the value of X if a = 25 and b = 11, Round to the nearest tenth.
Answers
Answer:
x = 19.9
Step-by-step explanation:
These kinds of problems have a specific formula.
Formula: outside (whole) = outside (whole)
We could substitute our variables into this.
For the first line, our outside segment is b and the whole thing is a + b
For the second line, our outside segment is x, and the whole thing is x.
[tex]b (a+b) = x(x)\\11 (25+11) = x^2\\11 (36) = x^2\\396 = x^2\\\\x=\sqrt{396}[/tex]
The [tex]\sqrt{396}[/tex] = 19.8997487421
Rounding to the nearest tenth, your answer is 19.9

It says that "The larger the MAD, the greater variability there is in the data (the data is more spread out)." So History would actually be the most wrong one. Health is the lowest value so Health is correct.
Answer:
Health
Step-by-step explanation:
MAD = median absolute deviation
It measures how spread out a set of data is, and is less affected by extremely high or low values.
The bigger the variance, the more spread out the data points are.
The smaller the variance, the less spread out the data points are.
Therefore, the scores were closest together in Health, since this has the smallest MAD.

Answer:
13
Step-by-step explanation:
2 + 4 + 6 + 8 + ...... + 26
n = 13
Sum of first 'n' even numbers = n( n +1)
= 13 * 14
= 182
1 + 3 + 5 + 7 + .....+25
n = 13
Sum of first 'n' odd numbers = n²
= 13 * 13
= 169
2 + 4 + 6 + 8 + ... + 26 - (1 + 3 + 5 + 7 + ......+25) = 182 - 169
= 13

B. -6
C. 6
D. 1/6
Answers
Answer:D
Step-by-step explanation:
The slope of a line will be 1/6. Then the correct option is D.
What is the slope?The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.
Slope = (y₂ - y₁) / (x₂ - x₁)
The points are given below.
(-6,3) and (12,6)
(x₁, y₁) = (-6,3)
(x₂, y₂) = (12,6)
Then the slope of a line will be
Slope = (6 – 3) / (12 + 6)
Slope = 3 / 18
Slope = 1/6
Then the correct option is D.
