Evaluate cos0 if sin0= sqrt(5)/3 a. 9/5 b. 2/3 c. 5/9 d. 3/2

Evgesh-ka [11]

Solution given:

$\sin( \alpha ) = \frac{\sqrt{5} }{3}$

P=√5

h=3

b= $\sqrt{3 {}^{2} - \sqrt{5} {}^{2} }$

b=2

$\cos( \alpha ) = \frac{b}{h} = \frac{2}{3}$

Select the correct product. (x + 8)(y + 3) xy + 8x + 3y + 24 xy + 3x + 8y + 24 11xy 24xy

MAXImum [283]

(x + 8)(y + 3)

x*(y+3) + 8*(y + 3)

x*y + 3*x + 8*y + 3*8

xy + 3x + 8y + 24

So the correct product is = xy + 3x + 8y + 24, I guess the second expression.

I hope this helps.
