To find the measure of ∠s, we can use the relationship between the angles formed by rays originating from a common point.
Let's denote the angles as follows:
- Let ∠1 be the angle between the first ray and the second ray, which is given as 54 degrees.
- Let ∠2 be the angle between the second ray and the third ray, which we denote as s degrees.
- Let ∠3 be the angle between the first ray and the third ray, which is given as 80 degrees.
We know that the sum of angles around a point is 360 degrees. Therefore, we can set up the equation:
∠1 + ∠2 + ∠3 = 360 degrees.
Substituting the known values into the equation:
54 degrees + s + 80 degrees = 360 degrees.
Now, combine the known angles:
134 degrees + s = 360 degrees.
Now, isolate s:
s = 360 degrees - 134 degrees,
s = 226 degrees.
So, the measure of ∠s is:
m∠s = 226 degrees.
