To find:
sin(38°) = ?
a) cos(38°)
b) cos(52°)
c) tan(38°)
d) tan(52°)
Solution:
Let us use the trigonometric identities in the given
.
We have to find the value of sin(38°).
We know that sine trigonometric identity is given as:

....... (1)
Now, let us find out the values of trigonometric functions given in options one by one:

....... (2)
By (1) and (2):
sin(38°)
cos(38°).
...... (3)
Comparing equations (1) and (3):
we get the both are same.

The hypotenuse must always be c
