<u>Angles in a Triangle</u>
There are two basic relations of angles we need to recall:
- Supplementary angles add up to 180°
- Internal angles of a triangle add up to 180°
Note a, b, and c are the internal angles of the triangle. The angle c is what is needed to a+b to complete 180°, thus:
c = 180 - ( a + b )
Also, note c and d are supplementary angles. Again, c is what is needed to d to complete 180°, thus
c = 180 - d
From the two relations above, it follows that:
a + b = d

Step-by-step explanation:
When two lines intersect, (in this case it's a ray and a line), they form a linear pair. Here, we know that because those two angles form a linear pair. Solving for x we have :
Answer:
The combined weight is 13 31/40.
Step-by-step explanation:
Given:
Adam buys a box of stuff that weighed 6 3/8. if he buys box of fruit that weighed 7 2/5.
Now, to find the combined weight.
So, we change the mixed fraction to improper first:
Weight of box of stuff = .
Weight of box of fruit = .
Then, by adding to get the combined weight:
Therefore, the combined weight is 13 31/40.
