What is the measure of arc BC?<br> 130<br> 65<br> 32.5<br> 180
ale4655 [162]

Answer:

The measure of arc BC is 130° ⇒ 1st answer

Step-by-step explanation:

In a circle:

  • The measure of an arc is equal to the measure of the central angle subtended by it
  • The measure of an arc is equal to double the measure of the inscribed angle subtended by it
  • Central angles subtended by the same arc are equal in measures
  • Inscribed angles subtended by the same arc are equal in measures
  • The measure of central angle is double the measure of the inscribed angle which subtended by its arc

∵ Angle BDC is an inscribed angle

∵ It is subtended by the arc BC

- By using the 2nd fact above

∴ The measure of arc BC = 2 × the measure of ∠BDC

∵ The measure of angle BDC is 65 degree

∴ The measure of arc BC = 2 × 65°

∴ The measure of arc BC = 130°

The measure of arc BC is 130°

The answer is yes.

Plug 4 in for the value of n so you have 4+8 is less than it equal to 13. And since 12 is less than 13 it is true, and a solution to the inequality.

1. An AMTRAK train travels at 125 mph. Convert this into miles per minute.
Vikki [24]
1) 125mph 
miles per minute
= 125/60
= 25/12
= 2.083 miles per minute

2) 10mph
miles per second
= 10/60/60
= 1/360 feet per second 

3) 2 megabytes per second
= 2*60*60
= 7200 megabytes per hour
