A plane flies in a direction of 24.5 degrees South of West at 290 mph. It encounters a 30.5 mph wind that is heading 21 degrees East of North. On a coordinate plane, three vectors are in quadrant 3. A ground vector is about 20 degrees from the x-axis, the air vector labeled 290 miles per hour is 24.5 degrees from the x-axis. Wind vector is 30.5 miles per hour from the terminal point of the air vector to the terminal point of the ground vector. It forms a 21 degree angle with a vertical line.

Select the correct ground speed for the plane (rounded to the nearest mph).

279 mph
281 mph
262 mph
269 mph

269MPH

Step-by-step explanation:

I had to sacrifice and guess on the quiz, but this was the right answer

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

no ,sorry if you needed it but you can ask and try to see if any one will anwser ,

by good luck mark me as brainliest

have a nice day
