Answer:

This would bring you to $160.00. This is because you initially had $20.00, because of the $13 and $7. Then, your family gave you a total of $140.00, and 140 + 20 = 160.

How to find angles on two Line intersect

Ivan

Hello!

Vertical angles are always congruent

This means that 3x - 35 = 130

We can solve this algebraically

3x - 35 = 130

Add 35 to both sides

3x = 165

Divide both sides by 3

x = 55

The angle AOB and AOC are supplementary which means they add to 180

First we have to find what angle AOB equals

3(55) - 35 = 130

We can subtract 180 by this number to get angle AOC

180 - 130 = 50

Angle AOC is 50

The answers are x = 55 and AOC = 50

Hope this helps!

gladu [14]

$the\ smaller\ angle= \frac{3}{8} \cdot 160^0=\frac{3}{8} \cdot \frac{160^0}{1} = \frac{3\cdot20^0}{1} =60^0\\ \\a=360^0-(160^0+60^0)=360^0-220^0=140^0$
