Answer: Choice A) Add 3.8 to both sides of the equation
Explanation:
If we knew the value of w, then we would replace it and apply PEMDAS.
However, we don't know the value of w, so we undo each step of PEMDAS going backwards.
We start with the "S" of PEMDAS, and undo the subtraction. To undo subtraction, you apply addition. To undo that "minus 3.8" we add 3.8 to both sides.
120/210 = 0.57
0.57 x 60 = 34.2
34 hours and 12 minutes
Step-by-step explanation:
the angle is greater than 180 degrees so it makes it an obtuse triangle
