(- 5, - 6 ) or (- 5, 10 )

using the distance formula

d = √(x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (1, 2 ) and (x₂, y₂ ) = (- 5, y )

d = √(- 5 - 1 )² + (y - 2 )² = 10

d = √36 + (y - 2 )² = 10

square both sides

36 + (y - 2 )² = 100 ( subtract 36 from both sides )

(y - 2 )² = 64

take the square root of both sides

y - 2 = ± 8 ( add 2 to both sides )

y = 2 ± 8

y = 2 + 8 or y = 2 - 8 ⇒ y = 10 or y = - 6

coordinates of A = (- 5, - 6) or (- 5, 10 )

I need help this is urgent!!
harina [27]
If you need an equation it is -3.4x=21.5

You simply divide both sides by -3.4 to get x=-6.32



if that's not right then just get on a calculator and calculate by doing what I said to divide

Answer:

y = 3 cm and x = 2.5 cm

Step-by-step explanation:

As we can see it is a parallelogram so

y = 3 cm (being opposite sides of parallelogram)

Now while calculating the diagonal we can use the Pythagoras relation. i.e

perpendicular (p) = 4 cm (IH)

Base (b) = 3 cm (FI)

Hypotenuse (h) = FH = ?

We know by using Pythagoras theorem

h = √ p² + b²

= √ 4² + 3²

= √ 25

= 5 cm

Here we got FH = 5 cm

so the value of x will be 2.5 cm as the diagonal bisects.

Hope it will help :)
