Q. A farmer plans to install solar collection panels to provide winter heating for the livestock. The most efficient panel angle for winter heating in the farm's region is 60∘ relative to ground level. If an individual panel is 67 inches (in) long and installed on the ground according to these instructions, what is the height, in in, of the upper edge above the ground?Choose 1 answer:(A) 33.53in(B) 33.52in(C) 33.5in(D) 31343in
Trigonometry Calculation: To find the height of the upper edge of the solar panel above the ground, we can use trigonometry. The length of the panel is the hypotenuse of a right-angled triangle, and the height above the ground is the side opposite the 60∘ angle. We can use the sine function to find this height.
Sine Function Equation: The sine of an angle in a right triangle is equal to the length of the side opposite the angle divided by the length of the hypotenuse. Therefore, we can write the equation: sin(60∘)=67 inchesheight
Substitute Values: We know that sin(60∘) is equal to 23. So, we can substitute this value into our equation: 23=67 inchesheight
Solve for Height: Now, we solve for the height by multiplying both sides of the equation by 67 inches: height=67 inches×(23)
Final Height Calculation: After performing the multiplication, we get: height=267×3 inches height=33.5×3 inches The simplified expression for the height is 33.53 inches, which corresponds to answer choice (A).
