Answer:
Therefore radius is 84 units.
Step-by-step explanation:
Given:
arc length = 56 pie
Central angle = θ = 120°
pi = 3.14
To Find:
Radius = r =?
Solution:
If the θ measured in degree then the arc length is given as
Where r = radius, θ = Central angle
On substituting the values we get
Therefore radius is 84 units.
In order for the Line m to be parallel with Line n :
Angle (3x + 5)° should be Equal to Angle 65°
Because they are Corresponding Angles and If two parallel lines are cut by a Transversal , The Corresponding angles should be Equal.
⇒ (3x + 5)° = 65°
⇒ 3x = 65 - 5°
⇒ 3x = 60°
⇒ x = 20°
Answer:
B) vector of the form (2,r, (2-5r)/4)
Step-by-step explanation:
(2,b,c) is orthogonal to (1,-5,-4) if
2*1-5b-4c=0, i.e,
5b+4c=2
We have equation with two variables, so we know that we wil have infinity lot solutions.
Let’s b be some real number r, so we have:
4c=2-5r, i.e,
c=(2-5r)/4.
So there is infinite lot of othogonal vectors of the form: (2, r, (2-5r)/c)) where r is any real number.

You just input 9*3 into a calculator and hit ‘equals’ 8 times, since there are 8 20-minute increments in 2 hours and 40 min.
