Question

if sin²Ø+3cos²ø=2 so what is the value of Ø​

Answer 1

Answer:

angle=45

Explanation:

sin²Ø+3cos²ø=2

sin²Ø+cos²ø+2cos²ø=2(sin²Ø+cos²ø=1)

1+2cos²ø=2

2cos²ø=1

cos²ø=1/2

cosø=1/root2

So, angle=45

Answer 2

Answer:

Hope it helps you, please mark me as brainliest.

Explanation:

45

sin²Ø+3cos²ø=2

sin²Ø+cos²ø+2cos²ø=2(sin²Ø+cos²ø=1)

1+2cos²ø=2

2cos²ø=1

cos²ø=1/2

cosø=1/root2

So, angle=45
