= 63.43° to the nearest hundredth

Step-by-step explanation:

The three sides of a right-angled triangle have specific names:

The 3 trigonometric ratios are:

For the given triangle we are given the OPPOSITE side to the angle, the ADJACENT side to the angle, and need to find the angle.

Therefore, we would use the trig ratio:  

Substituting the values from the triangle:  

⇒  

⇒  

⇒ 63.43494882...

So = 63.43° to the nearest hundredth

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
