Answer 1

Step-by-step explanation:

So, I make an addition also based on suggestions provided. My main error was to start to consider the right angle, instead I have to start considering θ=α°, and increse it till θ=90°, one side become smaller till zero, and the other side become bigger till equal to h, therefore cos α=0h=0

HOPE IT HELPS!!
