Answer:

a=49

Step-by-step explanation:

The angle having value (a+49)\textdegree is the exterior angle.

<em><u>Exterior angle of a triangle is equal to the sum of the other two opposite angles.</u></em>

Hence

a+49=a+a\\\\a+49=2a\\\\2a=a+49\\\\2a-a=49\\\\a=49

Answer:

at matilda's new job, she will make a rounded salary of $69,000 per year.

Step-by-step explanation:

when solving a problem like this, you have to take her current salary ($64,000 per year) and multiply it to the salary increase percentage by first turning the percentage into a decimal. to turn the percentage into a decimal, you imagine a tiny dot to the right of the 8 like this:

8.

and then you have to move that little dot to the left two times recreating it into .08. you multiply .08 (the salary increase percentage) by her current salary ($64,000) and then also add that number to matilda's current salary to come up with the answer you can round. I'll give you an example of my proscess just so I can give a clear visual of my explanation.

step one:

$64,000

x .08

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

5,120

step 2:

$64,000

+$5,120

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

$69,120

step 3:

$69,120 is rounded up to the nearest thousands is approximately $69,000

answer: $69,000
