Answer:

The measure of the smaller arc is 36\°

Step-by-step explanation:

we know that

The measurement of the external angle is the semi-difference of the arcs which comprises

Let

x-----> the measure of the bigger arc

y----> the measure of the smaller arc

we know that

32\°=\frac{1}{2}(arc\ x-arc\ y)

we have

arc\ x=100\°

substitute the values and solve for arc y

32\°=\frac{1}{2}(100\°-arc\ y)

64\°=(100\°-arc\ y)

arc\ y=100\°-64\°=36\°

Korvikt [17]
The change from 3/4 to 4/10 is found by obtaining and applying the LCD:

15/20 to 8/20 is a negative change, and the amount of the change was -7/20.

We compare this result to the original value, 15/20, to obtain the percentage change in the fraction:
