Answer 1

Hi friend
--------------
Your answer
------------------------

Let the angle be x.

Then, it's complementary angle = (90 - x).

Then,
----------

According to the question,
----------------------------------------

x + (90 - x)/2 = 75

=> x + 90/2 - x/2 = 75

=> x - x/2 = 75 - 45

=> x/2 = 30

=> x = 30 × 2

=> x = 60°

Therefore,
------------------

The answer is option C. 60° .
