Matt cut a circle into 8 equal sections he drew an angle that measures the same as the total measure of the angle Matt drew?
professor190 [17]
The answer is 135°.

The circle has 360°. If it is divided into 8 equal sections, the measure of the angle of each section is 45°:
360° / 8 = 45°

Matt drew an angle that measures the same as the total measure of the 3 sections in the circle. So, the measure of the angle Matt drew is 135°:
3 * 45° = 135°

A plane flies at x miles per hour in still air. Flying with a tailwind, its speed is 485 miles per hour. Against the wind, its a
Svetradugi [14.3K]

Answer:20mph

Step-by-step explanation:

speed of plane = x mph

Speed of plane with wind = 485 mph

So therefore, speed of wind =

485 - x

Speed of plane against wind = 445 mph

So therefore, speed of wind =

x - 445

So therefore, equating the 2 equations of speed of wind

485 - x = x - 445

Collect like terms

485 + 445 = x + x

930 = 2x

2x = 930

x = 930/2 = 465 mph

Speed of wind = x = 465mph

So we put this value on any of the equations for speed of wind

Speed of wind = x - 445 = 465 - 445

= 20 mph

So therefore, speed of wind = 20mph
