Answer:
A) 
B) 
Step-by-step explanation:
a) <u><em>According to Outside Angles theorem:</em></u>
=> m∠VYW = 
Where mVX = 79, VW = 173
=> m∠VYW = (173-79)/2
=> m<VYW = 94/2
=> m∠VYW = 47 degrees
b) <u><em>According to Angles of Intersecting Chords Theorem:</em></u>
=> m∠VZW = 
Where m∠VZW = 64, VW = 51
=> 64 = 1/2(51+XY)
Multiplying both sides by 2
=> 64*2 = 51+XY
=> 128 = 51+XY
=> XY = 128-51
=> XY = 77 degrees
The value of n that will make the expression equal is 13
<h3>Equations and expression</h3>
Equations are expressions separated by equal sign
Given the equation
11n = 143
Divide both sides by 11 to have;
11n/11 = 143/11
n = 13
Hence the value of n that will make the expression equal is 13

Answer:
About 8.6 units.
If you count up and sideways, it would be 12, but then there is some stuff we need to calculate at the end because it's not fully.
