Let
x--------> <span>the unknown scale size
we know that
N 1---------> 2.618
N 2---------> x
N 3---------> 1
N 4---------> 0.618
to obtain the size N 4 ----> multiply the size N 3 by 0.618
so
to obtain </span> the size N 2 ----> multiply the size N 1 by 0.618
size N 2=2.618*0.618------> 1.6179
x=1.618
the answer is
the unknown scale size is 1.618
If a central angle measures 57 degrees, based on the angle-arc relationship, the measure of its intercepted arc = 57 degrees.
<em><u>Recall:</u></em>
- The image attached below shows the relationship between the measure of the central angle and its intercepted arc.
- Measure of central angle = its intercepted arc.
Thus, if the measure of a central angle = 57 degrees, based on the angle-arc relationship, the measure of its intercepted arc will also be 57 degrees.
