Answer:
x=80
Step-by-step explanation:
The sum of interior angles in a quadrilateral is 360°
the square represents a right angle= 90 degrees
124+66+90=280
360-280=80
x=80
U need to show an example of the tiles in order for people to answer this
It would be 80% since it decreases 20% each year so 20*4 is 80 so it’s 80%
A is a 5th degree polynomial.
Their speed of separation will be equal to the sum of their speeds because they are in opposite directions.
Speed of separation = 40 + 50 = 90 miles per hour
Time = distance / speed
Time = 405 / 90
Time = 4.5 hours
