Answer:
m∠4 = 55°
Step-by-step explanation:
From the figure attached,
m∠DBC = m∠BCA + m∠BAC [Exterior angle of a triangle equals the sum of the remote interior angles]
m∠4 = 30° + 25° = 55°
Therefore, m∠4 = 55° will be the answer.
Answer:
solution set = {5/3 , 14/3}
Step-by-step explanation:
Given that:
y=4x-2 _________ eq1
y=x+3 ----------------- eq2
Subtracting eq 2 from eq1 we get:
0 = 3x - 5
By simplifying we get:
3x = 5
x = 5/3
Now putting value of x in eq2 we get:
y = 5/3 + 3
Taking LCM to make denominator same
y = 5/3 + 9/3
y = 14/3
So the solution set = {5/3 , 14/3}

The volume of a cone by definition is given by:
V = (pi * r ^ 2 * h) / (3)
Where,
r: radio
h: height
Clearing the height of the original cone we have:
h = (3 * V) / (pi * r ^ 2)
Substituting values:
h = (3 * 1875) / (pi * (40) ^ 2)
h = 1.119058194
We now look for the scale factor:
K = 16/40
Simplifying:
K = 4/10
K = 2/5
We apply the scale factor to the new volume:
V '= ((k ^ 3) * (pi * r ^ 2 * h)) / (3)
Substituting:
V '= (((2/5) ^ 3) * (pi * (16) ^ 2 * (1.119058194))) / (3)
V '= 19.2 cm ^ 3
Answer:
the volume of a similar cone with a radius of 16 cm is:
V '= 19.2 cm ^ 3
Answer:
instead of the 4, you can put the 80 and do the 20x4?
Step-by-step explanation:
i dont know if you can do that for whatever ur doing, just a suggestion
I lost my train of thought, but i was thinking of something like that
Answer:
First You add all given angles up to equal 180 to give you x then you plug x into equations
Step-by-step explanation:
A= 125 degrees
C= 35 degrees
