the size of a rectangular computer screen is determined by the length of its diagonal. tom buys a 52cm screen that is 33 cm high
marta [7]

Answer:

40.20cm approx

Step-by-step explanation:

Step one

given data

We are told that the dimension of a computer screen

diagonal= 52 cm

height= 33cm

Length = ?

Required

The length of the base of the screen

Step two

Let us use Pythagoras theorem to find the length of the base

Hyp^2= Opp^2+ Adj^2

52^2= 33^2+ L^2

2704= 1089+L^2

L^2= 2704-1089

L^2= 1615

L=√1615

L= 40.20cm approx

<u>The length is 40.20cm approx.</u>

Help me please number 7 (please show work)
astra-53 [7]

Answer:

m<H=30 degrees by the Triangle Sum Theorem, so <H=<V. <G=<U, they are right angles. If GH=UV, triangle FGH=triangle TUV by the ASA.

x=3  and y=8

Step-by-step explanation:

H equals 30 by 180-150=30 (getting 150 by adding 60 and 90)

I know this is not much of a answer, but I hope it helps a little.

To the nearest hundreth, what is the length of line segment AB?
FinnZ [79.3K]

Answer:

option (4)

Step-by-step explanation:

Calculate the length using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = A(2, 2) and (x₂, y₂ ) = B(- 6, 4)

AB = \sqrt{(-6-2)^2+(4-2)^2}

      = \sqrt{(-8)^2+2^2}

      = \sqrt{64+4}

      = \sqrt{68}

       ≈ 8.25 ( to 2 dec. places )
