What is the measure of arc BC?
130
65
32.5
180

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

Step-by-step explanation:

In a circle:

∵ 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°

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
