Refer to the figure to complete the following item. Given: PB tangent PV, PU secants

angle1=30 and mSTarc= 20, then mVUarc=___​

80°

Step-by-step explanation:

Since, If two secants intersect outside the circle, then the measure of the angle formed is one half of the difference  of the measures of the intercepted arcs.

In the given diagram,

Chord VS and chord UT are intersecting externally,

Also, ∠SPT is the angle formed by the intersection of these chords.

Thus, by the above property,

⇒ Measurement of the arc VU= 80°.

the answer for this question is 38
