If sin θ=.55 what is the value of cos θ and explain why

MatroZZZ [7]

Answer:

$cos(\theta)=(+/-)0.84$

Step-by-step explanation:

we know that

$sin^2(\theta)+cos^2(\theta)=1$ ----> by trigonometric identity

we have

$sin(\theta)=0.55$

substitute

$(0.55)^2+cos^2(\theta)=1$

$cos^2(\theta)=1-(0.55)^2$

$cos^2(\theta)=0.6975$

$cos(\theta)=(+/-)\sqrt{0.6975}$

$cos(\theta)=(+/-)0.84$

Remember that

If the sine of angle theta is positive, then the angle theta lie on the I Quadrant or II Quadrant

therefore

If the angle theta is on the I Quadrant the cosine will be positive

If the angle theta is on the II Quadrant the cosine will be negative

An architect designs a rectangular flower garden such that the width is exactly two-thirds of the length. If 390 feet of antiqu

Ksenya-84 [330]

Length (L): L

width (w): (2/3)L

Perimeter (P) = 2L + 2w

390 = 2(L) + 2(2/3)(L)

1170 = 6L + 4L

1170 = 10L

117 = L

width (w): (2/3)L = (2/3)(117) = 2(39) = 78

Answer: width = 78 ft, length = 117 ft
