You have to see which onw is bigger
Angle XYZ 67 degrees = (1/2) (247 - XZ)
67 = (1/2) (247) - (1/2) (XZ)
(1/2) (XZ) = (1/2) (247) -67
XZ = 247 -134
XZ = 113 degrees
Answer is Equation A

So with this, you'll be using a proportion to solve it. And here's what your equation will look like:
![\frac{30}{x} =\frac{x}{24}](https://tex.z-dn.net/?f=%20%5Cfrac%7B30%7D%7Bx%7D%20%3D%5Cfrac%7Bx%7D%7B24%7D%20%20)
Firstly, you'll need to cross-multiply. Your equation will look like this: ![720=x^2](https://tex.z-dn.net/?f=%20720%3Dx%5E2%20)
For this, all you need to do is square root, and your answer is
, however this answer can be simplified further.
![\sqrt{720} =\sqrt{30*24} =\sqrt{5*6*6*4}=\sqrt{5*3*2*3*2*2*2} =4*3\sqrt{5} =12\sqrt{5}](https://tex.z-dn.net/?f=%20%5Csqrt%7B720%7D%20%3D%5Csqrt%7B30%2A24%7D%20%3D%5Csqrt%7B5%2A6%2A6%2A4%7D%3D%5Csqrt%7B5%2A3%2A2%2A3%2A2%2A2%2A2%7D%20%3D4%2A3%5Csqrt%7B5%7D%20%3D12%5Csqrt%7B5%7D%20%20)
In short, your answer is ![12\sqrt{5}](https://tex.z-dn.net/?f=%2012%5Csqrt%7B5%7D%20%20)
Answer:
125%

Answer:
![-3y^2 - 8y-12](https://tex.z-dn.net/?f=-3y%5E2%20-%208y-12)
Steps:
Simplify each term.
![-5y^2-9y-4+2y^2+y-8](https://tex.z-dn.net/?f=-5y%5E2-9y-4%2B2y%5E2%2By-8)
Simplify by adding terms.
![-3y^2-8y-12](https://tex.z-dn.net/?f=-3y%5E2-8y-12)
<em>good luck, hope this helps :)</em>
