The answer to your question is answer A. 3m
Answer:
<h3>lt = lo/cos²θ</h3>
Step-by-step explanation:
Given the intensity of the transmitted light It and θ are related by the equation Cosθ= √ Io/It, we are to write lt as a function of lo
Given the equation
Cosθ= √ Io/It
Let us make lt the subject of the formula;
square both sides of the equation
(Cosθ)²= (√ Io/It)²
cos²θ = lo/lt
cross multiply
ltcos²θ = lo
divide both sides by cos²θ
ltcos²θ/ cos²θ= lo/cos²θ
lt = lo/cos²θ
Hence the expression of lt as a function of lo is lt = lo/cos²θ

Answer: The TV is 24 inches tall
Step-by-step explanation: The question has provided the diagonal and the width of the rectangle shaped television. From this bit of information, we can deduce that the diagonal of the rectangle (television) is also the Hypotenuse (26 inches) while the the other two sides are the Length and the Width (10 inches).
For every right angled triangle, we can apply the Pythagoras theorem to solve for any unknown side. The theorem states that
AC² = BC² + AB²
Where AC is the hypotenuse (longest side)
26² = 10² + AB²
676 = 100 + AB²
Subtract 100 from both sides of the equation
576 = AB²
Add the square root sign to both sides of the equation
√576 = √AB²
24 = AB
Therefore, the height of the television is 24 inches
