Question

A computer monitor is 23 inches which is the diagonal distance across the screen.If the screen measures 13 inches in height,what is the actual width of the screen to the nearest inch?

Answer 1

Answer:

width = 19 inches

Step-by-step explanation:

Pythagorean theorem

23^2 = 13^2+x^2

529 = 169+x^2

x^2 = 360

x = 18.97

Answer 2

width = 19 inches

                            23^2 = 13^2+x^2

                                                        529 = 169+x^2

                                                                                x^2 = 360

                                                                                                 x = 18.97
