Question

TUULLU. O A curve acts at degree angle, then curve is called an orthogonal trajectory of the family of curves. Answer A. 30 B. 90 c. 45 D. 60​

Answer 1

Given :  A curve cuts at _____ degree angle, Then  curve is called an orthogonal trajectory of the family of curves.

To Find : Fill in the blank

A. 30 B. 90 c. 45 D. 60​

Solution:

A  curve, which cuts  member of a given family of curves at right angles, is called an orthogonal trajectory of the family of the curves.

A right angle has a measure of 90 degree

Hence

A curve acts at  90 degree angle, Then  curve is called an orthogonal trajectory of the family of curves.

90 will come in the blank space.
