Answer: It is said to be an obtuse angle.
Step-by-step explanation:
Angles under 90 degrees are called acute angles.
Angles that are equivalent with 90 degrees are right angles.
Angles that measure more than 90 degrees but under 180 degrees are called obtuse.
Angle that have the same measure as 180 degrees are straight angle.

Step-by-step explanation:
Its what my calc said..
Natural numbers are our counting numbers. the numbers we see in nature. you can count 1,2,3,4 flowers. or 1,2,3,4,5,6,7,8 pedals on the flowers. etc they are our positive integers
whole numbers are numbers that can be written as an integer. 4/2 6/3 etc
so if it cant be written as an integer, it cant be a positive integer

Answer:the speed of the wind is 20 miles per hour.
Step-by-step explanation:
A Plane flies at x miles per hour in still air. This means that the normal speed of the plane is x miles per hour.
Let y represent the speed of the wind.
Flying with a tailwind, it's speed is 485 miles per hour. This means that
the total speed of the plane would be x + y. Therefore
x + y = 485 - - - - - - - - 1
Against the wind, it's air speed is only 445 miles per hour. This means that
the total speed of the plane would be x - y. Therefore
x - y = 445 - - - - - - - - - 2
Adding equation 1 and equation 2, it becomes
2x = 930
x = 930/2 = 465
Substituting x = 465 into equation 1, it becomes
465 + y = 485
y = 485 - 465
y = 20 miles per hour
