The first thing you should see in this case is that the triangles are proportional.
We have then that:
((a) / (c)) = ((d) / (a))
Step 1:
Go a multiplying:
((a) / (c)) * (a) = (d)
Step 2:
Pass c multiplying:
(a) * (a) = (d) * (c)
Step 3:
Same basis, exponents are added:
a ^ (1 + 1) = (d) * (c)
Step 4:
a ^ 2 = c * d
Finally
((a) / (c)) = ((d) / (a)) -------> a ^ 2 = c * d
For this case, we must find what amount represents 75% of 96.
Making a rule of three we have:
96 -------------> 100%
x ---------------> 75%
Where the variable "x" establishes the amount that represents 75% of 96.
Thus, 72 represents 75% of 96.
To find equivalent expressions that represent the same value as the 75% of 96, you should look for expressions that result in "72"
Answer:
72
<span>Two Angles are Supplementary if they add up to 180 degrees.
let angle 1=x
let angle 2=112+x
x+112+x=180
2x=180-112
hence x= 34

Why they add up is because you have to add up the whole numbers and then carry over the .3 to the other side.
Yes. M+3=-5, subtract 3 from both sides: -5-3=-2: m=-2. M=-2 is the same as m=-2 :)
