Answer:
is this good?? i mean is it correct
The top angle (10x+10) is equal to the angle below the lowest line and the skewed line. However, the 4x+2 is on the other side. But both together add up to 180° (a straight line).
So 10x+10 = 180-(4x+2) is the formula you're looking for.
Solving it:
10x+10 = 180-(4x+2) =>
10x+10 = 178-4x =>
14x = 168 =>
x = 12
Look up the theory for F angles and Z angles.
Answer:
59.99 minutes
Step-by-step explanation:
4 hours divided by 28 mins = 8.57142857 (rounded to 8.57)
7 x 8.57 = 59.99.
