Question

22. If Sin theta =Cos theta (theta is acute ) then what is the value of
theta ? (1 mark)



​

Answer 1

Answer:

sin theta = cos theta

sin theta / cos theta = 1

tan theta = 1 ------(1)

tan 45 = 1----(2)

from (1) & (2)..

theta = 45°

Answer 2

Answer:

Hope this helps!

Step-by-step explanation:

We know that,

Sin O = Cos(90-O)

But here, Sin O = Cos O

=> O= 90-O

=> 2O = 90

=> O = 45

Therefore, theta is 45 degree. theta is shown by the symbol O.
