Question

abcd is a trapezium in which ab parallel to bc and bc is parallel to x-axis if angle abc=60 and ab=ad, calculate the slopes of ab, dc, bd and ac.

Answer 1

Step-by-step explanation:

Suppose a line makes an angle A with X axis. Then A is known as angle of inclination of the line

Its slope = tan A

1. Since the side AB Parallel to X axis

its angle of inclination with x axis is 0 degree

Slope of AB = tan (0) = 0

2.Since the side BC perpendicular to X axis its angle of inclination with X axis is 90 degrees

Slope of BC = tan (90) = infinite

3. Since the diagonal AC makes an angle 45 degrees with X axis

Slope of AC = tan (45) = 1

I hope this answer helps you
