A man 2 m high observes the angles of elevation of the rops of house and a window on its sode are 45 and 60 respectively. If the top is at height of 12m above the ground , find the height.
Answers
Answer:
The height of the window = x + 2 = 4.23 + 2= 6.23m
Step-by-step explanation:
The angle of elevation of the top of the house and the window is 60 and 45 degree.
We can proceed as drawing a diagram as a man of height 2m and a building of total height 12m.
draw a horizontal line along the height of a man so that it touches building at height 2mtill the window height we assume its height as 'x' from the man's height.distance till the top from the window will be 'y'we don't know the distance between man and the building let it be 'b'
[tex]\frac{x}{b}=tan 45[/tex] =1
x=b .............(1)
total height of the building is given as 12m
x + y + 2=12
x + y = 10 .....................(2)
[tex]\frac{x+y}{b} =\frac{x+y}{x }[/tex] = tan 60
[tex]\frac{10}{x} = \sqrt{3}[/tex]
x = [tex]\frac{10}{\sqrt{3} }[/tex] ≈ 5.77m
y = 10 - [tex]\frac{10}{\sqrt{3} }[/tex]
y= 10(1-[tex]\frac{1}{\sqrt{3} }[/tex] ) ≈ 4.23m
The height of the window = x + 2 = 4.23 + 2= 6.23m

If the sum of a triangle equals 180 degrees we’ll go off of that by doing this.
(7x+8)+(5x+2)+(7x-1)=180
7x+8+5x+2+7x-1=180
19x+9=180
19x=180-9
19x=171
19x/19=171/19
x=9
With that let’s find each angle,
I’ll just label them A, B, C.
A: (7x+8)
7(9)+8
63+8=71
B: (7x-1)
7(9)-1
63-1=62
C: (5x+2)

45+2=47

is 0.25 greater than 3/8
Answers
Answer:
no 0.250 is not greater than 3/8
Step-by-step explanation:
because when you make 3/8 into a decimal it becomes 0.375 so no
Answer:
No. 0.25 is not greater than 3/8
Step-by-step explanation:
Convert 3/8 to a decimal.
1/8 = 0.125 in decimal form.
Multiply this by 3.
3/8 = 0.375.
0.375 > 0.250
Your answer will be 0.25 < 3/8

In Triangle XYZ, A is the midpoint of XY, B is the midpoint of YZ, and C is the midpoint of XZ.
Also, AY = 7. BZ = 8, and XZ = 18. What is the perimeter of Triangle ABC?
Make sure you explain why and show all your work.
Answers
Answer:
The perimeter of triangle ABC is 33.
Explanation:
AY = 7 is half of the line of XY so we would then multiply 7 by 2:
7 x 2 = 14
and we would then do this to all of our numbers:
8 x 2 = 16
18 x 2 = 36
now we make a full equation for the answer of the perimeter of triangle XYZ:
14 + 16 + 36 = 66
66 is the perimeter of triangle XYZ.
We would then divide this answer by 2 to find the perimeter of ABC because it is half of XYZ:
66 ÷ 2 = 33
The perimeter of triangle ABC is 33

. Your friend claims that it is not possible to have a glide reflection if you have one translation followed by two reflections. Is your friend correct? Explain your reasoning.
Answers
Answer:
Yes my friend is correct
Step-by-step explanation:
You cannot have a glide reflection if you have one translation which is followed by two ( 2 ) reflections .
This is because Glide reflection is made up of one ( 1 ) reflection in line with a single translation along the same line
Glide reflection is known as an opposite isometry of the Euclidean plane
Glide reflection is a single operation that involves a reflection over a line and followed by a translation.
Your friend's claim is correct.
From the definition, we can deduce that glide reflection consists of:
1 reflection1 translationThis means that: 1 translation and 2 reflections is not a glide reflection
Hence, your friend's claim is correct.

Step-by-step explanation
The product of a number and negative 7/10 is 1/2 can be written as 1/2=(7/10)x, with this equation, multiply by the reciprocal, 10/7, to make the right side of the equation just x. On the left side, multiply 1/2 by 10/7 because when you do something on one side, you must do it on the other. 1/2 times 10/7 equals 5/7. Leaving you with x=5/7

The solution of the given equation [tex](4)^{3\sqrt{x} -2}[/tex] + 1 = 9 will be x = 1.08.
What is a equation?An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.
Given is the following equation -
[tex](4)^{3\sqrt{x} -2}[/tex] + 1 = 9
The given equation is -
[tex](4)^{3\sqrt{x} -2}[/tex] + 1 = 9
[tex](4)^{3\sqrt{x} -2}[/tex] = 8
Assume 3[tex]\sqrt{x}[/tex] = n. Then, we can write the equation as -
(4)ⁿ ⁻ ² = 8
(4)ⁿ ÷ (4)² = 8
(4)ⁿ x 1/(4)² = 8
(4)ⁿ = 8 x 16
(2)²ⁿ = (2)³ x (2)⁴
2n = 3 + 4
2n = 7
n = 7/2
3[tex]\sqrt{x}[/tex] = 7/2
[tex]\sqrt{x}[/tex] = 7/6
x = 1.08
Therefore, the solution of the given equation [tex](4)^{3\sqrt{x} -2}[/tex] + 1 = 9 will be
x = 1.08.
