a wide screen television display measures approximately 15 inches high and 27 inches wide. a television is advertised by giving the approximate length of the diagonal of its screen. how should the television be advertised?

a. 36 inches
b. 31 inches
c. 30 inches
d. 21 inches

If you draw a line diagonal from one top corner to the opposite bottom corner you will have made 2 triangles. Then you can use the Pythagorean theorem to figure out the diagonal measure (or hypotenuse of the triangle. c squared=15 squared + 27 squared c squared= 225+729 c squared= 954 c= square root of 954 c=30.88 I would round that up to 31 inches

B.31 inches, I got this from 30.88 and I rounded.
1st. Draw a line diagonal from one top corner to the opposite bottom corner(you will have 2 triangles)
2nd.Pythagorean theorem to figure out the  hypotenuse of the triangle.
 c^2=15^2 + 27^2 c^2= 225+729 c^2= 954 c= square root of 954 c=30.88, aka 31 inches.

It is 2 out of 8 she will pick green and 3 out of 7 she will pick green but red and green would be 5 out of 5 so 50% chance
