What is the correct classification for ∠QPS?

rewona [7]

∠QPS is part of the right angle, and it takes 90 - 21 degrees of it.
90 - 21 = 69°

Now take 69 and add 22, the rest of ∠QPS.
69 + 22 = 91

∠QPS is 91°, which is larger than a right angle, 90°, so that means it is an obtuse angle.

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.
