Answer: $\frac{1}{2}$

Step-by-step explanation:

With unlike denominators find the Least Common Denominator (LCD)

LCD = 12

Multiplying numerators and denominators to get the LCD in all fraction denominators

$=\frac{3x3}{4x3}-\frac{1x4}{3x4}+\frac{1}{12}$

Then rewriting the equation with the equivalent fractions

$=\frac{9}{12}-\frac{4}{12}+\frac{1}{12}$

With like denominators we can operate on just the numerators

$=\frac{9-4+1}{12} =\frac{6}{12}$

Simplifying the answer

$=\frac{1}{2}$

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

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°
