Adam drew two same size rectangles and divided them into the same number of equal parts. He shaded 1/3 of one rectangle and 1/4

MArishka [77]

he divided each rectangle in 12 identical parts

for the first rectangle he shaded 1/3 of 12 = 4 parts

for the second rectangle he shaded 1/4 of 12= 3 parts

so 12= 3*4 leads to a minimum of 12 parts

Cos(0)=square root 3/3, sin 0<0. what is the value of sin0

abruzzese [7]

Answer:

sin θ = $\frac{\sqrt{6} }{3}$

Step-by-step explanation:

Given that,

cos θ = $\frac{\sqrt{3} }{3}$

From the trigonometric functions,

cos θ = $\frac{adjacent}{hypotenus}$

⇒ adjacent = $\sqrt{3}$ , and the hypotenuse = 3

Let the opposite side be represented by x, applying the Pythagoras theorem we have;

$/hyp/^{2}$ = $/adj/^{2}$ + $/opp/^{2}$

$/3/^{2}$ = $(\sqrt{3} )^{2}$ + $x^{2}$

9 = 3 + $x^{2}$

$x^{2}$ = 9 - 3

= 6

x = $\sqrt{6}$

Thus, opposite side = $\sqrt{6}$

So that,

sin θ = $\frac{opposite}{hypotenuse}$

= $\frac{\sqrt{6} }{3}$

Therefore,

sin θ = $\frac{\sqrt{6} }{3}$
