Question

if sin ∅=⅘ then find Cos∅​

Answer 1

Answer:

Find an answer to your question if sin theta =4/5 then find cos theta. ... Sin A= 4/5=prependicular/hypotenuse CosA = Base/ ...

Missing: ⅘ ‎| Must include: ⅘

Answer 2

Answer:

cos = 3/5

Step-by-step explanation:

sin = P/ H

= 4/5

P = 4 ; H = 5 ; B = ?

By Phythagorus theorem,

H^2 = B^2 + P^2

5 × 5 = B^2 + 4 × 4

25 = B^2 + 16

B^2 = 25 - 16

B^2 = 9

B = 3

cos = B/H

= 3/5
