Which of the following is equivalent to Square root -63
asambeis [7]

Answer:

3i \sqrt{7}

Step-by-step explanation:

The imaginary unit is i=\sqrt{-1}.

Now 63 itself is not a perfect square but 63 does contain a factor that is.

63=9×7 and 9 is a perfect square.

So \sqrt{-63}=i \sqrt{63}.

i \sqrt{63}=i \sqrt{9 \cdot 7}=i \sqrt{9} \sqrt{7}=i(3) \sqrt{7}=3i \sqrt{7}

What is the measure of X! Please help if you know how to do this!
deff fn [24]

Answer:

28°

Step-by-step explanation:

You're given that line DE and line FG are parallel and KL and FG are perpendicular. Then you can find out angle ∠BAC by using the vertical angles property: ∠BAC=62°. Then since KL and FG are perpendicular ∠ABC = 90°. So you find the angle ∠BCA by finding the sum of interior angles: 62+90+∠BCA=180, therefore ∠BCA is 28°. Finally, ∠x or ∠JCG = 28 because ∠JCG and ∠BCA are vertical angles and congruent.

Need help with a math question
Mekhanik [1.2K]

Answer:

z =3\sqrt{13}

Step-by-step explanation:

In the figure you can identify up to 3 straight triangles.

To solve the problem, write the Pythagorean theorem for each triangle.

<em>Triangle 1</em>

13^2 = z^2 + x^2

<em>Triangle 2</em>

z^2 = y^2 + 9^2

<em>Triangle 3</em>

x^2 = y^2 + 4^2

Now substitute equation 2 and equation 3 in equation 1 and solve for y.

13^2 = y^2 + 9^2 + y^2 + 4^2

13^2 = 2y^2 + 9^2 + 4^2

169 = 2y^2 + 81 + 16

2y^2 =72

y^2 =36

y =6

substitute the value of y in the second equation and solve for z

z^2 = 6^2 + 9^2

z^2 = 36 + 81

z^2 = 117

z = \sqrt{117}

z =3\sqrt{13}
