Answer:
The correct answer is 47 degrees.
Step-by-step explanation:
Use cosine.
cos(x)= adj/hyp
cos(x)=19/28
x=arccos(19/28)
Use a calculator
x is approximately 47 degrees.
You add the left side 2/7+2/7+2/7= 6/7
You add the right side 1/2+1/2+1/2+1/2+1/2+1/2= 6/2 and that equal 3 when simplified.
Now you multiply 6/7 * 3 =2.5 Letter D
The answer is 82
