Circle A is shown. Secant W Y intersects tangent Z Y at point Y outside of the circle. Secant W Y intersects circle A at point X. Arc X Z is 105 degrees and arc W Z is 175 degrees. In the diagram of circle A, what is the measure of ∠XYZ? 35° 70° 75° 140°

35

Step-by-step explanation:

Here, we can use use the formula for an angle formed by secants or tangents theorem. The formula is

m∠1=

In circle A,

m∠1 = ∠XYZ

x = arc WZ

y = arc XZ

m∠1= 1/2 (175-105) degrees

= 35 degrees

answer:

1. 0.04

2. 0.15
