The square root of 20? You'd use Pythagorean Theorem.
Answer: B
Step-by-step explanation:
The picture in the attached figure
we have
arc XV = 68°∠YUV = 36°
we know that
The measure of the external angle is the semidifference of the arcs that it covers.
therefore
∠YUV =[arc VY-arc XV]/2
arc VY=[2*∠YUV]+arc XV----------> [2*36]+68---------> 140°
the answer is
the measure of arc VY is 140°
0.08/10= 0.008. 0.08 is ten times as great as 0.008
