Answer:
x = 40
Step-by-step explanation:
Angles SRT and STR are congruent, so they have the same measure.
The measure of <SRT is 20, so the measure of <STR is also 20.
Angles STR and STU form a linear pair. Two angles that form a linear pair are supplementary, so their measures add up to 180.
m<STR + m<STU = 180
20 + 4x = 180
4x = 160
x = 40
 
        
             
        
        
        
Answer:
a) XY , XVY
b) 248°
c) UV , UY
d) 6√5 = 13.42
Step-by-step explanation:
a) The minor arc is XY
    The major arc is XVY
b) ∵ The measure of the minor arc is 112°
     ∵ The measure of the circle is 360°
     ∴ The measure of the rest arc = 360 - 112 = 248°
c) UV is the tangent to the circle
    UY is the secant to the circle
d) ∵ UV is a tangent to the circle at V
     ∵ UY is a secant to the circle
     ∴ (UV)² = (UX) × (UY)
     ∵ UX = 9 and XY = 11 ⇒ ∴ UY = 11 + 9 = 20
      ∴ (UV)² = 9 × 20 = 180
       ∴ UV = √180 = 6√5 = 13.42
