Circle O is shown below. The diagram is not drawn to scale? If Angle r is 32, what is angle O?

1 answer:

5 0

We have to find the measure of angle O.
We already know that ∠R = 32°.
The measure of the inscribed angle ( here ∠ R ) is half the measure of the central angle ( here ∠ O ).
Therefore:
∠ O = 2 · 32° = 64°
Answer:
B ) 64°

The midpoint of AB is M(1, 3). If the coordinates of A are(4,1), what are the coordinates of B?

Oxana [17]

Answer:

B(-2,5)

Step-by-step explanation:

$\frac{x + 4}{2} = 1 \\ 2 \times \frac{x + 4}{2} = 1 \times 2 \\ x + 4 = 2 \\ x = 2 - 4 \\ x = - 2 \\ \frac{y + 1}{2} = 3 \\ 2 \times \frac{y + 1}{2} = 3 \times 2 \\ y + 1 = 6 \\ y = 6 - 1 \\ y = 5$

Hope that this is helpful.

Have a nice day.

A lake has 10,000 fish.when a fishman scoops up his net ,he catches 500 fish. Suppose 150 of the 500 fish in his net are salmon.

Inessa [10]

You need x 20 to get to 10000, so do the same with 150 and get 3000, so it is 3000/10000
