3C + 5A = 115
C + A = 33
A = 33 - C
3C + 5(33-C) = 115
3C + 165 - 5C = 115
-2C = -50
C=25
25+A=33
A=8
C=25, A=8
Hi there !!
The sum of two numbers is the number obtained by adding two given numbers. However, the opposite numbers are two numbers whose sum is equal to 0.
Example : (+3) + (-3) = 0
The answer is :
(+2) + (-2) = 0 because (-2) is the additive inverse of (+2).

Now, for a rhombus, all sides are the same length, and the diagonals bisect the vertex they cut, so they cut them in halves, and they also meet at right-angles, and cut each other in halves as well
that means, if the angle is 108, the shorter diagonal will cut that in two equal angles, of 54 each, check the picture below
and since they each other cut in halves where they meet, one side of the shorter diagonal will then be half of 9, or 9/2 or 4.5
since the angle is in degrees, make sure your calculator is in Degree mode
