The area of a 25 inch tv screen is 300 in.². the area of a 40 inch tv screen is 768 in.². the area of the smaller screen is what percentage of the area of the larger screen?

39.0625%

Step-by-step explanation:

The area of a 25 inc TV screen is 300in²

The area of a 40 inch TV screen is 768in²

Percentage of area of the smaller screen to larger screen is;

300/768 × 100 = 39.0625%

step-by-step explanation:

find the angular size of the equatorial radius of the earth, if the horizontal parallax of the sun

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
