The measure of ∠angle B when Angle C is inscribed in circle O and AB is a diameter of circle O, is 19 degrees.

<h3>What is triangle angle sum theorem?</h3>

According to the triangle angle sum theorem, the sum of all the angle(interior) of a triangle is equal to the 180 degrees.

In the image attached below:

  • Angle C is inscribed in circle O.
  • AB is a diameter of circle O.

The measure of the angle A is,

m\angle A=71^o

The measure of the angle C in a semicircle is,

m\angle C=90^o

The sum of all the angle(interior) of a triangle is equal to the 180 degrees. Thus,

\angle A+\angle B+\angle C=180\\90+\angle B+71=180\\\angle B=180-90-71\\\angle B=19^o

Thus, the measure of ∠angle B when Angle C is inscribed in circle O and AB is a diameter of circle O, is 19 degrees.

Answer:

301.6 ft³

Step-by-step explanation:

The volume (V) of a cone is calculated using the formula

V = \frac{1}{3} × area of base × perpendicular height (h)

h can be calculated by using Pythagoras' identity in the right triangle

with hypotenuse = 10 and legs 6 and h, thus

h² + 6² = 10²

h² + 36 = 100 ( subtract 36 from both sides )

h² = 64 ( take the square root of both sides )

h = \sqrt{64} = 8

Hence

V = \frac{1}{3} × π × 6² × 8

   = \frac{1}{3} × 288π = \frac{288\pi }{3} ≈ 301.6

Out of 75,000 voters in a constituency 65%
serious [3.7K]
<h3>Answer:</h3>

\large\boxed{35\%\,\text{did not vote;}\,48,750\,\text{voted}}

<h3>Step-by-step explanation:</h3>

In this question, we're trying to find the amount of people that did not vote and the percentage of people that didn't vote.

We know that 65% of people voted and percents are out of 100%.

We would subtract 65 form 100 to get out percentage that didn't vote.

100-65=35

35% of people didn't vote.

Now, we can solve the next question.

A total of 75,000 people voted. What we're going to have to do is find how much of 75,000 is 65%.

We would do this by multiplying 75,000 by 0.65

75,000*0.65=48,750

This means that 48,750 people voted.

<h3>I hope this helped you out.</h3><h3>Good luck on your academics.</h3><h3>Have a fantastic day!</h3>
