Copy the shape and fill in the missing angle. Sow the work. Thanks.
Answer:
The first triangle can be solved using the triangle sum theorem.
There is a vertical angle, so 75 is the angle at the bottom left. 45 is also a vertical angle. Now we have 75+45+x=180, where x is the missing angle. x is 60.
A straight line = 180 degrees, so 60+79+y, where y is unknown, is equal to 180. y is 41. Now use the triangle sum theorem for the triangle to the right. 41+68+z, where z is unknown, = 180. Z is 71.
Now the last part is to find the question mark. A straight line is 180 degrees, so 71+"?" is 180. Simplify to find that "?" is 109.

4 points Item 5 is unpinned. Click to pin. A cylindrical oil drum is 2.1 meters high and has a radius of 0.9 meters. How many cubic meters of oil can the drum hold? (volume)
Answer:
53.44 cubic meters
Step-by-step explanation:
A cylindrical oil drum is 2.1 meters high and has a radius of 0.9 meters. How many cubic meters of oil can the drum hold? (volume)
Volume of a cylinder = π × r² × h
r = 0.9 meters
h = 2.1 meters
= π × (0.9m)² × 2.1m
= 53.44 cubic meters
Therefore, the volume of the cylindrical oil drum = 53.44 cubic meters
im trying to help my little brother with his homework and I don't remember how to convert 54 to 5/4
Answer:
divide 54 by 9, and you get 6. this is because for every 5 sam gets bethan will get 4. if you add, that, you will get the total amount for 1 share. since there are 6 shares, you multiply that by the amount of eros sam and bethan gets each share.

Near the equator, the Earth rotates approximately 3 4 kilometers every 3 2 seconds. What is the speed of Earth's rotation near the equator?
Answer:
Speed = 1.0625 km / sec
Step-by-step explanation:
Distance = 34 kilometers
Time = 32 seconds
Speed = ?
The relationship between these quantities is given as;
Speed = Distance / Time
Inserting the values;
Speed = 34 km / 32 sec
Speed = 1.0625 km / sec
Why does sin30° equal 1/2?
Step-by-step explanation:
it's easy to prove in any right triangle with a 30° angle, the side opposite to that angle is half the hypotenuse. CA (1/2)BC, CA/BC=1/2
Step-by-step explanation:
Take an equilateral triangle of side.
Bisec it through a vertex and the midpoint of the opposite side.
You now have two right-angled triangles with angels 30° , 60°, 90° with the edge opposite the 30° of length 1/2 and hypotenuse 1. So
sin (30°) = 1/2/1= 1/2.
Answer: The right angled triangle you describe has angels of 45 degrees, not 30 degrees.
What you proved is sin 45 = 1\2 , which is correct.
Throughout Lewis Carroll's book, Alice's Adventures in Wonderland, Alice's size changes. Her normal height is about 50 inches tall. She comes across a door, about 15 inches high, that leads to a garden. After drinking a potion, Alice's height changes to 10 inches so she can visit the garden. How tall would the door have been in Alice's normal world? Justify your answer and provide mathematical evidence.

The length of one diagonal of a rhombus is 8 cm. The area of the rhombus is 72 cm2. What is the length of the other diagonal of the rhombus?
Answer:
18 cm
Step-by-step explanation:
From the question above,
Area of a rhombus
A = d₁d₂/2.................. Equation 1
Where A = area of the rhombus, d₁ = length of one diagonal, d₂ = length of the other diagonal
make d₂ the subject of the equation
d₂ = 2A/d₁............... equation 2
Given: A = 72 cm², d₁ = 8 cm
Substitute these values into equation 2
d₂ = (2×72)/8
d₂ = 144/8
d₂ = 18 cm.

What is the side length of the smallest square plate on which a 30 cm chopstick can fit along a diagonal without any overhang? The approximate side length of the square plate is black cm.
Answer: 21.21 cm
Step-by-step explanation:
Given
length of diagonal on the square is 30 cm
Suppose a is the side length of the square
and length of diagonal is given as [tex]a\sqrt{2}\ units[/tex]
So,
[tex]\Rightarrow a\sqrt{2}=30\\\\\Rightarrow a=\frac{30}{\sqrt{2}}=21.21\ cm[/tex]
Thus, the side length of the square is 21.21 cm

Joe stands at the top of a cliff and looks down at a 49-degree angle
of depression at a boulder that is 17 m away from the bottom of the cliff.
How tall is the cliff?
11.2 m
14.8 m
19.6 m
25.9 m
Answer:
Step-by-step explanation:
tan49=h/17
h=17tan49
h=19.6 m
The height of the cliff is 19.6 m tall
A right angled triangle is a triangle (has three sides and three angles) in which one of the angles measure 90°.
Trigonometric ratios is used to show the relationship between the sides of the right angled triangle and its angles.
Let h represent the height of the cliff. Let θ = 90 - 49 = 41°. Hence:
tan(41) = 17/h
h = 17 / tan(41) = 19.6 m
Therefore the cliff is 19.6 m tall

What is the volume of the prisms below?
What equation would you use for the last picture?
Answer:
8) 131.118in^3
9) 18cm^3
Step-by-step explanation:
8) Volume of the prism = Length * Width * height
Volume of the prism = 4.1in * 8.2in * 3.9in
Volume of the prism = 131.118in^3
Hence the volume of soil that will fill the prism is 131.118in^3
9) Volume of the triangular prism = Base Area * Height of prism
Base Area = 1/2bh
Base Area = 1/2 * 4 * 3
Base Area = 6cm^2
Height of the prism = 3cm
Volume of the prism = 6cm^2 * 3cm
Volume of the prism = 18cm^3
What is the slope-intercept equation for this
standard form equation?
(Y-intercept needs to be positive)-
(Giving Brainliest for Correct Answer-)
6x - 3y = 12
Answer:
Y = 2x - 4
Slope is 2.
Y-intercept is -4.
Step-by-step explanation:
To find slope in standard form, take -A/B. So 6 is A, -3 is B. -(6/-3) = 2.
And to find the y-int, take C/B. C is 12. So, 12/-3 = -4.
Or you could also rearrange the equation. . .
6x - 3y = 12.Subtract 6 from both sides. -3y = -6x + 12Divide by -3 to isolate the y. y = 2x - 4.If R(y=-1 ° T<0,3>)(X) → X'(3, -2), what were the coordinates of X?

A. exactly 22 days
B. more than 22 days
C. at most 22 days
D. less than 22 days
25 PTS!!
Answer:(c)
Step-by-step explanation:
Given
Inequality is [tex]10x+18\leq 238[/tex]
Subtract [tex]18[/tex] from both side of the inequality
[tex]\Rightarrow 10x+18-18\leq 238-18\\\Rightarrow 10x\leq 220[/tex]
divide both sides by 10
[tex]\Rightarrow \frac{10x}{10}\leq \frac{220}{10}\\\Rightarrow x\leq 22[/tex]
Therefore, maximum value of x can be 22 i.e. at most 22 days
