Question

pls it's very urgent ​

Answer 1

Answer:

30 degrees

Step-by-step explanation:

We have 2sin^2(o) + cos^2(45) = tan^2(45)

We know the value of cos^2(45) and tan^2(45)

Lets substitute them here

So the equation turns out to be 2sin^2(o) +1/2 =1

So 2sin^2(o) = 1/2

sin^2(o) = 1/4

so sin(o) can be either + 1/2 or -1/2

But we know that O lies between 0 to 90

So sin(o) =1/2

And (o) = 30 degrees

Answer 2

Answer:

The answer is

: 30 degrees
