Question

if ∛tan∅=1 then find the value of Sin²∅ + cos²∅
pls do this the first one to answer, i will mark as brainliest.
i need this urgently

Answer 1

Answer:

the answer is 1

Step-by-step explanation:

sin^2theta +cos^2theta is always equal to 1

Answer 2

Answer:

1

Step-by-step explanation:

√3tan∅=1

or, tan∅=1/√3

or, ∅=30° (since tan30°=1/√3)

sin^2∅ + cos^2∅ = sin^2(30°) + cos^2(30°)

= (1/2)^2 + (√3/2)^2

= 1/4 + 3/4

= 4/4

= 1
