PLEASE HELP ME WITH THESE FOUR QUESTIONS TYSMMM!!! THANK YOU

Dima020 [189]

Answer:

$107^\circ, 133^\circ, 20^\circ, \text{and}, 23^\circ$

Step-by-step explanation:

9. For the lines 'm' and 'n' to be parallel the sum of interior angles should be 180 degrees that is:

$x+73^\circ=180^\circ$

$x=107^\circ$

10. For the lines 'm' and 'n' to be parallel the alternate exterior angles should be equal that is:

$147^\circ=x+14^\circ$

$x=147^\circ-14^\circ$

$x=133^\circ$

11. For the lines 'm' and 'n' to be parallel alternate angles should be equal that is:

$180^\circ-3x=2x+20^\circ$

Solving for 'x' we get:

$180^\circ-20^\circ=3x+2x$

$5x=160^\circ$

$x=32^\circ$

12. For the lines 'm' and 'n' to be parallel corresponding angles should be equal that is:

$(7x-11)^\circ=(4x+58)^\circ$

$7x-4x=58^\circ+11^\circ$

$3x=69^\circ$

$x=\frac{69}{3}=23^\circ$

Use the following work shown below to answer the following question.

zysi [14]

Answer:

$\frac{3 + \sqrt{3x} }{3 - x}$

Step-by-step explanation:

You can use the work they gave you and continue from there:

$\frac{\sqrt{3}(\sqrt{3}) + \sqrt{3}(\sqrt{x}) }{(\sqrt{3}) ^{2} - (\sqrt{x} )^{2} }$

First, simplify the numerator:

$\frac{3 + \sqrt{3x} }{(\sqrt{3}) ^{2} - (\sqrt{x}) ^{2} }$

Finally, simplify the denominator:

$\frac{3 + \sqrt{3x} }{3 - x}$
