A sailor on Ship A measures the angle between Ship B and the pier and finds it to be 35°. A sailor on Ship B measures the angle between Ship A and the pier and finds that it is 54°. What is the measure of the angle between Ship A and Ship B?

Given:

Angle between Ship B and the pier 35°.

Angle between Ship A and the pier 54°.

To find:

The angle between Ship A and Ship B.

Solution:

It is clear that location of pier, Ship A and Ship B forms a triangle as shown in below figure.

Let the angle between Ship A and Ship B be x.

According to angle sum property, the sum of all the interior angles of a triangle is 180°.

Therefore, the angle between Ship A and Ship B is 91°.

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
