An airplane is flying at an elevation of 5150 ft, directly above a straight highway. Two motorists are driving cars on the highw
Alecsey [184]

Answer:

The cars are 10702ft apart

Step-by-step explanation:

Height of the plane from the high way = 5150ft

Considering Triangle ABD, we will be using SOHCAHTOA

Tan = Opposite/ Adjacent

Tan 54° = Y/5150

Y = 5150*tan54°

Y = 7088 ft

Considering Triangle ADC, Tan = Opposite/ Adjacent is also applicable

Tan 34° = X/5150

X = 5150*tan 54°

X = 3614ft

The distance between the two cars = (X+Y)

= 7088 + 3614

= 10702ft

Alenkinab [10]

Responder:

- 30 ° C

Explicação passo a passo:

Dado que :

A temperatura diminui 1 ° para cada 200 m afastados da superfície terrestre

Temperatura na superfície da terra = 20 ° C

Temperatura atmosférica a uma altura de 10 km de. Superfície Terrestre :

Queda de temperatura para uma altura de 10 km de distância;

10km = 10 * 1000 = 10.000 m

1 * (10000/200)

1 * 50

= 50 ° C

Portanto ;

Temperatura da superfície terrestre - 50 ° C

20 ° C - 50 ° C

= - 30 ° C
