Can someone please help me?? trying to retake some questions If angle U = 8x + 9 degrees, and angle W = 8x - 5 degrees, then the measure of angle U is ___ degrees.

97 degrees

Step-by-step explanation:

We know that U and W add up to 180 degrees so we can write:

8x+9+8x-5=180

Simplify:

16x+4=180

We can figure out x from here!

x=11

Since x=11, we can plug that in and get:

88+9=97

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
