<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

Answer:
9 months
Step-by-step explanation:
8 sculptures in 6 months is 1 sculpture in 0.75 months.
8/8=1
6/8=0.75
1×12=12
0.75×12=9
Answer:
Total number of animals in the group = 170
Step-by-step explanation:
Let the number of sheep = a
Number of dragons in the group = 75
Number of dragons opposite dragons = 37
Number of sheep opposite to the dragon = 1
Number of sheep left = a - 1
Number of sheep opposite to sheep =
Since. number of sheep opposite to sheep is 10 more than of dragons opposite dragons,
= 37 + 10
a - 1 = 94
a = 95
Then total number of animals in the group = Total number of sheep + Total number of dragons
= 95 + 75
= 170
Therefore, total number of animals in the group are 170.
