What is the measure of 1 in the trapezoid? 110° 55° 165° 85°

 The correct option is (B) 55°.

Step-by-step explanation:  We are given to find the measure of angle 1 in the trapezoid shown in the figure.

We know that

one pair of sides of a trapezoid are parallel to each other.

As shown in the figure, the base of the trapezoid and its opposite side are parallel to each other.

Also, they are cut by a tranversal such that the angle 1 and the angle with measure 125°  are interior angles on the same side of the transversal.

So, the sum of the measures must be equal to 180°.

That is,

Thus, the required measure of angle 1 is 55°.

Option (B) is CORRECT.

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.
