a straight line = 180 degrees
so the missing angle is 180 - 130 = 50 degrees
Answer:
The third figure is the answer (Look to the attached figure
Step-by-step explanation:
* The point of symmetry means
- If a figure or graph can be rotated 180° about a point P
and end up looking identical to the original, then P is a point
of symmetry
- The same distance from the central point
but in the opposite direction.
* Lets look to the four answers
- In the 3rd figure first line up can be rotated 180° about a point P
and end up looking identical to the second line down, then P
is a point of symmetry
- The same distance from the point p
but in the opposite direction.
* The figure show the answer
Given:
Bobby put 1/3 of his lawn mowing money into his savings
He uses the remaining 2/5 to buy a video game.
He has $12 left.
To find:
The amount did he have at first.
Solution:
Let x be the initial amount.
Bobby put 1/3 of his lawn mowing money into his savings. So, the remaining amount is

He uses the remaining 2/5 to buy a video game. Then the remaining amount is





It is given that the remaining amount is $12.



Divide both sides by 2.


Therefore, Bobby have $30 at first.
There are 7 numbers.
Each number can be paired with the remaining 6 numbers.
7 x 6 = 42 different two digit numbers can be made.
