Triangles WXZ and XYZ that share side XZ with right angle XZW, WZ equals 16, XZ equals 12, and YZ equals 9 Since segment XZ is perpendicular to segment WY, angles WZX and XZY are both right angles and congruent. The proportion shows the corresponding sides are proportional, so the triangles are similar by the SAS Similarity Postulate.

16/9

Step-by-step explanation:

According to the SAS Similarity Postulate, if triangle WXZ and triangle XYZ are similar, it means the included angles are equal to each other or congruent to each other, while two corresponding sides are proportional.

Thus, we have:

WZ/YZ =XW/XY

<XZW is congruent to <XZY =90°

Thus, the proportion of the side would be:

WZ/YZ = 16/9

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
