You can find the area of a triangle by using this equation:
Area=(1/2)base x height
If you have the measurement for the bottom part of the sandwich, then you have your base. If you have the height of the sandwich then you have the height. Since the triangles are congruent when you find the area of one triangle, you are finding the area of the other triangle. To combine the areas of the triangles, just multiply the area of one triangle by 2.
It would be 68 degrees for each angle

Answer:
306
Step-by-step explanation:
There are 18 ways to pick the president
Now there are only 17 students left
there are 17 ways to pick the vice president
18 * 17 =306
There are 306 different ways to pick a president and vice president
First off, we can find the number that has to be increased by multiplying the original amount by 40%:
45×40%
=45×0.4
=18
We can then add the above amount to the original amount to find the toys they must sell:
45+18
=63
They must sell 63 toys to get the bonus.
Alternatively:
The total percenrage of toys need to be sold to get a bonus with the 40% increase:
=100%+40%
=140%
The amount of toys:
=45×1.4
=63
Therefore the answer is 63.
Hope it helps!
