The bearing of a point P from a point Q is 155°. Determine the bearing of Q from P

The bearing of Q from P is 335°

Step-by-step explanation:

The given bearing of point P from a point Q = 155°

The bearing of one point from another point is the measure of the angle in degrees of the direction of the line between the two points measured from the north

From the diagram drawn showing the bearing of point P from point Q, we have;

The alternate angle of the angle between the north direction and the line drawn from point P to point Q = 180° - 155° = 25°

Therefore, the bearing of point Q from point P = The angle at a point - The angle between the line from P to Q and a line pointing south direction

∴ The bearing of point Q from point P = 360° - 25° = 335°.

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
