The measure of the arc is given as π/2. See the explanation below.
<h3>What is an arc?</h3>
An "arc" is a curve that connects two points in mathematics.
It can also be depicted as a section of a circle. It is essentially a portion of a circle's circumference. An arc is a kind of curve.
<h3>What is the calculation for the above solution?</h3>
Note that the viewing angle is 45°.
Thus, the center angle is:
45 X 2 = 90°
Measure of the arc therefore is:
= (π/180°) x 90
= π/2

Mercury: 87 24/25
Venus 224 7/10
Mars 686 49/50
All we need to do is to convert fractions so they have a denominator of 10, 100, 1000 etc.
87 24/25 = 87 96/100
224 7/10 stays the same
686 49/50 = 686 98/100
Now we can easily convert them into decimals:
Mercury: 87.96
Venus: 224.7
<span>Mars: 686.98</span>
Answer:

Step-by-step explanation:
Intersection represents the elements present in both sets.
