Cos(theta) = adjacent/hypotenuse
cos(theta) = 6/20
cos(theta) = 0.3
Use the inverse cos or cos^-1 on your calculator to get the angle
theta = 72.5
we know that
total of sum of arc is 360
so, sum of both arc must be 360
so, we get

now, we can solve for x

............Answer
Answer:
X is greater than 4.6
Step-by-step explanation:
Answer:
The answer is option D.
Step-by-step explanation:
cos M = adjacent / hypotenuse
From the picture
b is the adjacent
x is the hypotenuse
so
cos M = b/x
