SOMEONE EXPLAIN FOR 100 POINTS AND BRAINLIEST! GEOMETRY HELP PLEASE!

Step-by-step explanation:

The top and bottom triangles have two congruent sides with different included angles.

The greater angle has greater opposite side.

The ∠DAC must be greater than zero but smaller than 48°.

Required inequality is:

So x has a value between 6 and 30

6 < x < 30

Step-by-step explanation:

The top and bottom triangles have two congruent sides with different included angles.

AB = AD and AC is common side.

The greater angle has greater opposite side.

The ∠BAC is greater than the ∠DAC as opposite side of the first (22) is greater than the opposite side of the second (16).

The ∠DAC must be greater than zero but smaller than 48°.

Required inequality is:

0 < 2x - 12 < 48

12 < 2x < 60

6 < x < 30

So x has a value between 6 and 30

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

1,918
