The size of the angle of a triangle are are in the ratio 2:4:9 calculate the size of the three angles in degree

1 answer:

3 0

Total Unit of Triangle = 2+4+9 = 15
Value of one unit = 180/15 = 12

So, Angles = 2(12) : 4(12) : 9(12) = 24 : 48 : 108

In short, Your Angles would be: 24, 48 & 108

Hope this helps!

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.
