If sin theta = cos theta , then theta is 45°
K4katana:
but how?
Sin theta is equal to cos theta if and only if theta is 45 °
in one case sinA=cosA i. e. 45° so theta or A=45° got it
okay thank you
yur wlc
Sin 45° = sin ( 90-45°) = cos 45°
It is possible only in this case
i got it thank you

If sinA= cosA
then A= 45
then A= 45
but how?
If sinA= cosA then P/H = B/H. So P=B. Thus triangle is now isoceles. Thus A = 45
thank you i got it
