A certain television is advertised as a 53-inch TV (the diagonal length). If the width of
zhenek [66]

The TV is 45 inches tall.

Step-by-step explanation:

The diagonal length of television = 53 inches

Width of TV = 28 inches

As TV is in rectangular or square shape, a diagonal will form a right triangle

Where,

Diagonal = hypotenuse = c = 53 inches

Width = base = b = 28 inches

Length = perpendicular = a

we will use pythagorean theorem to find the length.

a^2+b^2=c^2\\a^2+(28)^2=(53)^2\\a^2+784=2809\\a^2=2809-784\\a^2=2025

Taking square root on both sides

\sqrt{a^2}=\sqrt{2025}\\a=45

The TV is 45 inches tall.

Keywords: triangle, square root

Use two unit multipliers to convert 62 square centimeters to square inches
gtnhenbr [62]

Answer:

Step-by-step explanation:

You only need one, but to use two let's go from cm to mm an then mm to inches.  there are 100 mm^2 in a cm^2 so that's 100 mm^2/ 1 cm^2 and then there's  645.16 mm^2 in one square inch so that one will be 1 in^2/ 645.16 mm^2 so writing it out we get:

62 cm^2 * 100 mm^2/ 1 cm^2 *  1 in^2/ 645.16 mm^2

units all cancel out to get in^2 an then you just multiply 62*100/645.16 = 9.61 so that leaves us with 9.61 in^2.

Let me know if there's something you don't understand.
