Answer:

The option "C" is correct

#in my opinion#

Step-by-step explanation:

The size of a screen is generally measured diagonally.

Thus to find the diagonal length,

we take help from Pythagoras theorem

$i.e. \\ {h}^{2} = {b}^{2} + {p}^{2}$

where h (hypotenuse) is the diagonal length, b (base) is the length of horizontal side, and p (perpendicular) is the length of the vertical side of the TV,

THUS the diagonal length or hypotenuse

$h = \sqrt{ {b}^{2} + {p}^{2} } \\ \: = \sqrt{1024 + 324} \\ \: = \sqrt{1348} \\ \: = 36.7 \: (= aprox \: 37)$

I need to know what is the m< DBC?

Artist 52 [7]

Answer:

120

Step-by-step explanation:

The sum of the angles is 180 since it forms a straight line

2x+ x+90 = 180

Combine like terms

3x +90=180

Subtract 90 from each side

3x+90-90=180-90

3x= 90

Divide each side by 3

3x/3 = 90/3

x = 30

We want angle DBC = x+90

= 30+90

=120
