Question

if sin theta =3/4 and tan theta =9/2 then find cos theta​

Answer 1

Step-by-step explanation:

sinx=opp/hyp

tanx=opp/adj

so, cosx=2/4=1/2

Answer 2

Step-by-step explanation:

Sin theta = p/h

p/h=3/4. _ (1)

Tan theta = p/b

p/b=9/2 _(2)

cos theta =b/h

divide 1 by 2

p/h ÷ p/b = 3/4 ÷ 9/2

p/h × b/p = 3/4 × 2/3

b/p = 1/6

cos theta = 1/6

here's your answer
