θ = Drift angle sin θ = 20/400 θ = 2.866° Heading required = 357° Groundspeed = 400*cos(2.866) = 399.5 time = 900/399.5 = 2.25 hours

... no aliens. Nobody lives on other planets. Airplanes that go down are hit by demons because they need the airspace to fight...

a= -50√2i -50√2j -50√2i -50√2j + 50√2i +yj= -140j y= (-140+50√2)j velocity= w= 50√2i - (140 -50√2)j speed= ||w||≈ 99 km/hr

Draw the picture. I'm going to assume a flat earth - If not, it gets more complicated. Draw a horizontal line through the aircraft. Drop a vertical line from the aircraft to the ground. Label the know angles of depression...

Let x = the distance of the first fire to a point directly below the plane y = the distance of the second fire to a point directly below the plane Then distance between the fires is given by d = x + y 3200/x = tan(33), x = 3200/tan(33) y...

It the one labeled θ, I can be top, bottom, left or right, rotated triangles are considered the same triangle. What matters is it's position relative to the the other labeled angled and sides. for...

Remember the basic distance formula: D = RT Solve it for time: T = D/R Plug in your values: D : distance in miles (28) R : rate in miles per hour (185) T : time in hours T = 28/185...
