Work out the size of the angle marked X.
Give your answer correct to 1 decimal place.
Answers
Answer:
41.8°
Step-by-step explanation:
We solve using the Trigonometric function of Sine
Hypotenuse = 15cm
x = θ
Opposite = 10cm
sin θ = Opposite/Hypotenuse
sin θ = 10/15
θ = arc sin ( 10/15)
θ = 41.810314896°
θ = Approximately to 1 decimal place = 41.8°
Therefore, x = θ = 41.8°

PLEASE HELP PLEASE IM STUCK PLEASEEE
Answers
Answer:
Step-by-step explanation:
since it's a square we know the two sides are equal. So set them equal and solve for X
a)
4x + 3 = 3x +17
4x-3x = 17 -3
x = 14
Since we now know X plug it into the expression for the angle
b)
5(14) + 4y = 90 ( 90° b/c we know the angle is equal to that )
70 4y = 90
4y = 90-70
4y = 20
y = 20/4
y = 5
c)
we can find the perimeter by just plugging in X to either of the expressions for the side and then multiplying that by 4, since there are 4 sides
4(14) +3
56 +3
59
now times 4 for each side
59*4= 236

A right circular cone has a radius of 6 inches and a slant length of 10 inches. A right cylinder has a radius of 8 inches and a height of 12 inches. How many cones full of water are needed to fill the cylinder
Answers
Answer:
6.4 cones full of water
Step-by-step explanation:
Given data
Radius of cone= 6inches
Slant height= 10 inches
Volume of cone= 1/3πr^2h
V= 1/3*3.142*6^2*10
V= 1/3*3.142*36*10
V= 1/3*1131.12
V= 377.04 cubic inches
Radius of right cylinder= 8 inches
Height= 12 inches
Volume of cylinder= πr^2h
Volume= 3.142*8^2*12
Volume= 3.142*64*12
Volume=2413.056 cubic inches
Hence the number of cone full of water needed to fill the cylinder is
=Volume of cylinder/volume of cone
=2413.056/377.04
=6.4 cones full of water

2x-y=0 3x=2y=-3
I’m not sure the correct steps to solve.
Answers
Answer:
x = 3 and y = 6
Step-by-step explanation:
The given equations are :
2x-y=0 ......(1)
3x-2y=-3 .....(2)
We need to solve equations (1) and (2).
Equation (1) can be written as :
2x = y
Put the value of y in equation (2)
3x-2(2x)=-3
3x-4x = -3
-x = -3
x = 3
Put the valye of x in equation (1)
2(3)-y=0
y = 6
Hence, the value of x = 3 and y = 6.

The answer is "The Last choice".
Step-by-step explanation:
Please find the complete question in the attached file.
It is the phrase that perfectly represents the usage of a simulation for an estimate of the likelihood of the birthday of 2 randomly chosen persons on a Monday.
In a week there are 7 days, so seven choices are available, and just one Monday. Therefore, it is probable that [tex]\frac{1}{7}[/tex] will occur on a Monday to a birthday individual.
The first person will have a probability [tex]\frac{1}{7}[/tex].
The second person also has a probability [tex]\frac{1}{7}[/tex] .
