Question

Heya ❤

Can anyone say me how to find the inclination of line AB
for all the three question....

Please don't give irrelevant answers....!

Answer 1

Step-by-step explanation:

i. The line AB forms a triangle with the x - axis and the y - axis, by intersecting them at two points.

In the triangle formed, the angle between the x - axis and the y- axis is 90 degree

Since the sum of all angles of a triangle is 180 degree

, the sum of the other two angles will be 90 degree

As the other two sides of the triangle formed are congruent, the other two angles are equal and since their sum is 90 both are equal to 45 degree

Inclination of a line is the angle it makes with the x- axis.

Hence, inclination of line AB is 45 degree

ii. The line AB forms a triangle with the x - axis and the y - axis, by intersecting them at two points.

In the triangle formed, the angle between the x - axis and the y- axis is 90 degree

Since the sum of all angles of a triangle is 180 degree

, the sum of the other two angles will be 90 degree

As the other two sides of the triangle formed are congruent, the other two angles are equal and since their sum is 90 both are equal to 45 degree

Inclination of a line is the angle it makes with the x- axis.

Hence, inclination of line AB is 45 degree

iii. X + 2x + 90 = 180

X = 30

inclination = tan X

tan 30 degree = 1/ √3
