Point Z is the incenter of triangle RST. Point Z is the incenter of triangle S R T. Lines are drawn from the points of the triangle to point Z. Lines are drawn from point Z to the sides of the triangle to form right angles and line segments Z A, Z B, and Z C. Angle A S Z is (5 x minus 9) degrees and angle Z S B is 16 degrees. What is the value of x? x = 2 x = 3

9514 1404 393

  x = 5

Step-by-step explanation:

SZ is the angle bisector of angle S, so ...

  ∠ASZ = ∠ZSB

  5x -9 = 16

  5x = 25 . . . . . . add 9

  x = 5 . . . . . . . . .divide by 5

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.

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
