Answer:
The measure of one angle is
, and the measure of the other one is 
Step-by-step explanation:
Recall that supplementary angles are those whose addition renders 
We need to find the measure of two such angles whose difference is precisely
.
Let's call such angles x and y, and consider that angle x is larger than angle y, so we can setup the following system of equations:

We can now solve this by simply combining term by term both equations, thus cancelling the term in "y", and solving first for "x":

So, now we have the answer for one of the angles (x), and can use either equation from the system to find the measure of angle "y":

Answer:
x=-4
Step-by-step explanation:
x - 2x - 5 +4x = 7 + 6x
3x - 5 = 7 +6x
-3x -3x
-5 = 7 + 3x
-7 -7
-12 = 3x
-12/3= 3x/3
-4 = x
Angle 1 is also 54. 2 and 4 are verticals. 4 is 126
Well, first, you need to add up the amount of ten fridges and ten pianos. than you see if its heavier or lighter... > or <....... do you remember how to graph?
