Find the value of x.

nekit [7.7K]

Answer:

Step-by-step explanation:

Since this right angled triangle has two angles of 45, so according to theorem sides opposite to equal angles are equal

Applying Pythagoras theorem

(4√2)^2=(x)^2+(x)^2

32=x^2+x^2

32=2x^2

x^2=32/2

x^2=16

Taking sq root on both sides we get

x=4

Whats the distance between (-8,-7) (8,-4)

balandron [24]

To find the distance between points, use the distance formula.

Distance formula: $\sqrt{ (x_{2} - x_{1})^{2} + ( y_{2} - y_{1})^{2} }$

Plug in your values for $x_{2}, x_{1}, y_{2}, y_{1}$ using (-8, -7) and (8, -4) and solve.

$\sqrt{(8 - (-8))^{2}+(-4 - (-7))^{2}}$
$\sqrt{(8+8)^{2}+(-4+7)^{2}}$
$\sqrt{(16)^{2}+(3)^{2}}$
$\sqrt{256+9}$
$\sqrt{265}$ ≈ $16.28$

Answer:
Approximately 16.28 units.
