La medida de cada ángulo interno de un polígono regular es 140o. Determine la medida de cada ángulo central.
Answers
Answer:
Cada ángulo central tiene una medida de 40°.
Step-by-step explanation:
Un ángulo interno en un polígono regular comprende dos ángulos contiguos de igual medida de dos triángulos contiguos. Si el polígono regular tiene un ángulo interno de 140°, entonces cada triángulo tiene dos ángulos de 70°. El tercer ángulo corresponde al ángulo central. Por Geometría sabemos que la suma de las medidas de los ángulos internos de un triángulo es igual a 180°, entonces tenemos que la medida del ángulo central es:
[tex]\alpha = 180^{\circ} - 70^{\circ} - 70^{\circ}[/tex]
[tex]\alpha = 40^{\circ}[/tex]
Cada ángulo central tiene una medida de 40°.

Liz walks 1/2 mile in 20 minutes on Monday and 3 3/4 in 150 minutes on Sunday is this proportional or non -proportional
Answers
Answer:
proportional
Step-by-step explanation:
so if 1/2 is 20, 1/4 is 10, and 1 whole mile is 40.
40 + 40 + 40 + 10 + 10 + 10 = 150
because we used the reasoning from the first part and it turned out correct, it is proportional

How do you find the radius of a Tetrahedron?
My own question no answer choices.
No bit links plz. 15 points and plz describe well.
Answers
Answer:
The center of the tetrahedron divides each of the four heights (or medians) in the ratio 1:3 (in an equilateral triangle the corresponding ratio is 1:2). The smaller part is also the radius of the inscribed sphere. Therefore the radius of this sphere is one quarter of the height or 9 in your case.

(1 point) Find ⋅ if =⟨−1,0,1⟩ and =⟨4,5,2⟩ Is the angle between the vectors "acute", "obtuse" or "right"?
Answers
Answer:
Obtuse.
Step-by-step explanation:
If we have a vector v = (a, b, c)
The magnitude of the vector is:
|v| = √(a^2 + b^2 + c^2)
And the dot product of two vectors:
v = (a, b, c)
w = (c, d, e)
is:
v.w = |v|*|w|*cos(θ) = a*c + b*d + c*e
With that relation, we can find the angle between the two vectors.
In this case, we have:
v = ⟨−1,0,1⟩
then:
|v| = √( (-1)^2 + 0^2 + 1^2) = √2
And:
w = ⟨4,5,2⟩
then:
|w| = √( 4^2 + 5^2 +2^2) = √116
Then:
v.w = (√2)*(√116)*cos(θ) = (-1)*(4) + 0*5 + 1*2
(√2)*(√116)*cos(θ) = -4 + 2 = -2
(15.23)*cos(θ) = -2
cos(θ) = -2/15.23
θ = Acos( -2/15.23) = 97.5°
Then the angle is larger than 90°, so the angle is obtuse.
At a football game, a vender sold a combined total of 208 sodas and hot dogs. The number of hot dogs sold was 44 less than the number of sodas sold. Find the number of sodas sold and the number of hot dogs sold.
Answers
Answer:
the number of sodas sold and the number of hot dogs sold is 126 and 82 respectively
Step-by-step explanation:
Given that
The total of sodas and hot dogs sold is 208 sodas
And, the number of hot dogs was 44 less than the number of sodas sold
We need to find out the number of sodas sold and the number of hot dogs sold
Let us assume the number of sodas sold be x
So, the number of hot dogs be x - 44
Now as per the given question
x + x - 44 = 208
2x = 208 + 44
2x = 252
x = 126
So, the number of hot dogs is
= 126 - 44
= 82
hence, the number of sodas sold and the number of hot dogs sold is 126 and 82 respectively
