1. a) Find TR if PR=10m and QT=7m. b) Find the measure of angle R 2. an aircraft flies 400 km from a point O on a bearing of 025 and then 700 km on a bearing of 110 to arrive at B.

a) How far north of O is B?

b) How far east of O is B

c) Find the distance and bearing of B from O

what

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
