Help the question is on the image.

Phantasy [73]

Answer:

$\boxed {tan\theta = \frac{2}{3}}$

Step-by-step explanation:

Let's derive a formula :

⇒ Area (triangle) × 3 = Area (square)

⇒ 1/2(bh) × 3 = a²

∴ But a = h (shown in diagram)

⇒ 3/2(bh) = h²

⇒ h = 3b/2

Now, taking tan θ :

⇒ tan θ = b/h

⇒ tan θ = b/(3b/2)

⇒ tan θ = 2b/3b

⇒ tan θ = 2/3

guapka [62]

We know that

1½ cup of cleaner-------> (1*2+1)/2-----> 3/2 cup of cleaner

the ratio of cleaner to water=(3/2)/12---> 3/(2*12)--> 3/24--> 1/8
