Television sizes are based on the length of the diagonal of the television's rectangular screen. so, for example, a 70-inch television is a television having a diagonal screen length of 70 inches. if a 70 inch television's diagonal forms a 29° angle with the base of the screen, what is the vertical height (h) of the screen to the nearest inch?

34 inches.

Step-by-step explanation:

Length of diagonal AC = 70 inches

A 70 inch television's diagonal forms a 29° angle with the base of the screen i.e.∠ACD = 29°

Now we are supposed to find the vertical height of television.i.e.AB

So, we will use trigonometric ratio:

Using trigonometric ratios  

Thus the vertical height of the screen to nearest inch is 34 inches.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
