Verify
((1+sin)/tan)=((1+csc)/sec)

Step-by-step explanation:

(1+ sinθ)/tanθ = 1/tanθ + sinθ/tanθ

= cosθ/sinθ + sinθ/(sinθ/cosθ)

= cosθ/sinθ + sinθ×cosθ/sinθ

= cosθ/sinθ + cosθ

= cosθ(1/sinθ + 1)

= (1/sinθ + 1)/(1/cosθ)

= (cscθ+1)/secθ

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
