Question

If sin x = cos y, then x+y=45°, write true or false...​

Answer 1

Answer: False

Step-by-step explanation:

Given: sinx=cosy

To Find: Whether x+y= 45° is True or false

sinx=cosy

As per trigonometric formula, we can write sinx=sin(90°-y)

Provided x and y are acute angles

By eliminating sin from both the sides we get

sinx=sin(90°-y)

x=90-y

x+y=90°

The sum of x and y values comes 90°. However, in the given statement the sum of x and y values comes 45°.

Hence the given statement is false.
