x = 16 and y = 116

Step-by-step explanation

For the trapezoid, the sum of the adjacent side is 180. Hence;

6x+20 + 4x = 180

10x + 20 = 180

10x = 180-20

10x = 160

x = 160/10

x = 16

Also, the sum of opposite side is 180, hence;

4(16)+ y = 180

64 + y = 180

y = 180 - 64

y = 116 degrees

hence x = 16 and y = 116

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
