-105 hope this helps again lol
Answer:
a = 1.8 cm
Step-by-step explanation:
Here. we want to find the value of a
To do this, we are going to use the sine rule
it states that the ratio of a side and the sine of the angle that faces the side is a constant for all the sides of a triangle
From the diagram, we have that;
The angle facing a is;
180-15-105 = 60
So, we have that
a/sin 60 = 2/sin 105
a = 2sin 60/sin 105
a = 1.794 cm
opposite means the sign changes (from positive to negative or vice versa)
since a rational number includes both positives and negatives, then the opposite of a rational is also a rational.
For example: 
is a rational number. Its opposite is 
, which is also a rational number.
Hope this helped!
