Not sure if this is what you’re looking for but if its a right angle than the two streets are perpendicular.
The angle measurement would also be 90 degrees.

This is the correct answers
Step-by-step explanation:
But, as you know that
Then the equation (1) becomes
Multiply Numerator and Denominator by
then,
take cos y as common, then
Here, (1+cos y/cos y + 1) gets cancelled.
Then the remaining answer is cos y.
