Answer:

$45$ degrees

Step-by-step explanation:

Angles on a straight line add up to 180 degrees.

Thus, $x+3x=180$

$4x=180$

Divide both sides by 4:

$\frac{4x}{x} =\frac{180}{4}$

$x=45$

Help me plzzzzzzzzz<br> solve for x

Svet_ta [14]

Answer:

$7) \frac{x+20}{x}=\frac{46}{30}$

$30(x+20)=46x$

$30x+600=46x$

$46x-30x=600$

$16x=600$

$x=75/2$

$x=37.5$

---------------------

$8) \frac{10}{3x+1} =\frac{22}{7x-1}$

$10(7x-1)=22(3x+1)$

$70x-10=66x+22$

$70x-66x=22+10$

$4x=32$

$x=\frac{32}{4}$

$x=8$
