If x is the average of "the other 20 numbers", then their sum is 20x. Adding the 21st number makes the sum of all 21 numbers be 20x +4x = 24x.
The 21st number, 4x, is 4x/(24x) = 1/6 of the total of all numbers,
Answer:
60% of 5 is 3
Step-by-step explanation:
The measure of the arc WT in the circle is 51 degrees.
<h3>How to find the measure of an arc when tangent intersect?</h3>
The measure of the angle formed by the intersection of two tangents outside a circle is half the positive difference of the measure of the intercepted arc.
Therefore,
m∠RPS = arc RS - arc WT / 2
m∠RPS = 35°
arc RS = 121°
arc WT = ?
35 = 121 - x / 2
cross multiply
70 = 121 - x
70 - 121 = -x
x = 51°
Therefore,
arc WT = 51°
