The value of the cosine of an angle in Quadrant Il is given. cos theta= -2/5 What is sin theta? O- ✓29 5 V10 5 5 VI 21 5​

Step-by-step explanation:

Given

cosθ = -

Using the identity

sin²θ + cos²θ = 1 , then

sinθ = ±

       = ±

      = ±

      = ±

     = ±

Since θ is in second quadrant the sinθ > 0 , thus

sinθ =

step-by-step explanation:

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
