Step-by-step explanation:
Cause it is right
The painting would cost $ 387.45. Because 2'3"=24"+3"=27 inches and<span>3'5"=36"+5"=41 inches. The area will 1107 when 27 is multiplied with 41. The cost is obtained through multiplying 0.35 and 1107. Their product is 387.45. The painting costs $ 387.45

Answer:
Step-by-step explanation:
<u>Let's derive a formula</u> :
⇒ Area (triangle) × 3 = Area (square)
⇒ 1/2(bh) × 3 = a²
∴ But a = h (shown in diagram)
⇒ 3/2(bh) = h²
⇒ <u>h = 3b/2</u>
<u>Now, taking tan θ</u> :
⇒ tan θ = b/h
⇒ tan θ = b/(3b/2)
⇒ tan θ = 2b/3b
⇒ tan θ = 2/3
