Question

sintheta+tan²theta=sec ²​

Answer 1

$Sin\theta + tan^2\theta = sec^2\theta$

$Sin\theta=sec^2\theta-tan^2\theta$

$Sin\theta = 1$

$Sin\theta = Sin(90)$

$\theta = 90^o$

Answer 2

Answer:

Hey mate here is ur answer....

Please mark as brainliest dear....

Step-by-step explanation:

sin∅ + tan²∅ = sec²∅

sin∅ + tan²∅ = sec²∅

sin∅ = sec²∅ - tan²∅

sin∅ = 1

sin 90° = 1

∅ = 90°
