Question

if 1 sin ²A / cos²A= tan∅,there the value of∅is....​

Answer 1

Explanation:

1-sin square theta equal cos square theta

cos^2A /cos^2A=tan a

1=tan a

a =45° ans  

please mark me as brainliest

Answer 2

Answer:

if sin²A/cos²A =1

sinA/cos A= 1

sinA= cos A

therefore A= 45° since

sin 45= 1/✓2

cos 45 =1/✓2
