The central angle in the circle is ∠DAC,major arc is BED, minor arc is ADC and BC=(5π*BD)/18.

Given that BD is diameter of the circle and angle BAC is 100°.

We are required to find the central angle, major arc, minor arc, m BEC, BC.

Angle is basically finding out the intensity of inclination of something on the surface.

In the circle central angles are many like BAC and CAD. We can write CAD as DAC also.

Major arc of a circle is that arc whose length is larger than all other arcs in the circle.

In our circle the major arc is arc BED.

Minor arc of a circle is that arc whose length is smaller.

In our circle the minor arc is arc ADC.

We know that arc's length is 2πr(Θ/360)

In this way BC=2π*(BD/2)*100/360

=(5π*BD)/18

We cannot find angle BEC.

Hence the central angle in the circle is ∠DAC,major arc is BED, minor arc is ADC and BC=(5π*BA)/18.

help me!!! A polynomial that has 4 turning points is multiplied by another polynomial that has 1 zeros. What is the minimum degr
Anna71 [15]
The polynomial with 4 turning points has the degree of 4+1 = 5. Whatever number of turning points there are, add 1 and you get the degree.

The degree of the polynomial with one root or zero is 1

When you multiply polynomials, the degrees will add so 5+1 = 6 is the minimum degree of the new polynomial.

The final answer is 6.

Anastasy [175]

Answer:

C) 75

Step-by-step explanation:

I got this because what you have to do, they all have to add up to 180. so what you do is:

2x + 30 = 180

      -30    -30

2x = 150

2x/2 = 150/2

x = 75
