Which equation represents the value of x? x=100−y2−−−−−−−√ x=10+y2 x=10−y x=y2+100−−−−−−−√ Right triangle A B C with angle B as

Nostrana [21]

Answer:

Therefore the required value of x,

$x=\sqrt{(100-y^{2})}$

Step-by-step explanation:

Given:

ΔBC is a Right Angle Triangle at ∠ B = 90°

As ∠ B = 90° , AC will be the Hypotenuse

AC = 10 = Hypotenuse

BC = y = Longer leg ( say )

AB = x = Shorter leg ( say )

To Find :

x = ?

Solution:

In Right Angle Triangle Δ ABC , By Pythagoras Theorem we get

$(\textrm{Hypotenuse})^{2} = (\textrm{Shorter leg})^{2}+(\textrm{Longer leg})^{2}$

Substituting the given values we get

$10^{2}= x^{2}+y^{2} \\\\x^{2}=100-y^{2} \\\\\textrm{square rooting on both the side we get}\\\\x=\sqrt{(100-y^{2})}\\\therefore x=\sqrt{(100-y^{2})}\ \textrm{ which is the required value of x}$

Therefore the required value of x,

$x=\sqrt{(100-y^{2})}$

What two numbers multiply to -50 and add up to -23

umka2103 [35]

Answer:

-25 and 2

Step-by-step explanation:

x + y = -23

xy = 50, so y = 50 /x

x + 50/x =-23, x^2 +23x - 50 = (x-2)(x+25)

so 2 and -25

Plase dont awnser just for points

egoroff_w [7]

So 3 2/3 is about 3.67 so it would go in between 3.65 and 3.7. So it would be the second answer.
