Answer: 90 degrees
============================
Explanation:
Let x and y be the two angles. Because they are supplementary angles, this means x+y = 180. Also since we're told that the angle is its own supplement, we can say that y = x.
Consequently, we can replace y with x and solve for x like so:
x+y = 180
x+x = 180 .... y is replaced with x since y = x
2x = 180
2x/2 = 180/2
x = 90
This means y = 90 as well. As a check, note how
x+y = 90+90 = 180
which verifies our answer.

Answer:
60 lbs large and 25 lbs small box
Step-by-step explanation:
50 large and 50 small boxes = 50 * 85 = 4250
5150-4250 =900 lbs weigh of 15 big boxes,
1 big box= 900 divide 15 = 60 lbs
85-60= 25 lbs = 1 small box
