Answer 1

Step-by-step explanation:

$\mathfrak{ ty}$

$\implies{hgt}$

Answer 2

Answer:

5 tan θ = 4

tan θ = 4/5

cos θ - sin θ

cos θ + sin θ

multiply by 1/cos θ in numerator and denominator

1/cos θ (cos θ - sin θ)

1/cos θ (cos θ + sin θ)

cos θ - sin θ

cos θ cos θ

cos θ + sin θ

cos θ cos θ

1 - tan θ

1 + tan θ

1 - 4/5

1 + 4/5

1/5

9/5

1/9 ANSWER
