Complementary angles together form a 90 degree angle. I don’t understand the question to well, but if two angles are next to each other and one of them is ten degrees, the other angle would be 80 is Together they form a right angle. Does my explain make sense? Sorry I hope this helps

x+y=600
x=250
y=350

Answer:
6 dm
Step-by-step explanation:
Triangle DBE is similar to triangle ABC, so their side lengths are proportional.
DE/AC = DB/AB
The length of DB can be found from ...
DB +AD = AB
DB = AB -AD = (15 -10) dm = 5 dm
So, we can fill in the proportion:
DE/(18 dm) = (5 dm)/(15 dm)
DE = (18 dm)·(1/3) . . . . . . . . . . simplify, multiply by 18 dm
DE = 6 dm

Answer:
m = 3, n = -2.
Step-by-step explanation:
Substitute n = 3m - 11 in the second equation:
2m + 3(3m - 11) = 0
2m + 9m - 33 = 0
11m = 33
m = 3.
Substitute for m in n = 3m-11:
n = 3(3) - 11
n = -2.
