I believe they are called opposites.
Answer:
x=6
Step-by-step explanation:
We can write this as a ratio
x 9
---- = --------
10 15
Using cross products
15x = 10*9
15x = 90
Divide by 15
15x/15 = 90/15
x =6
54x+14= 43x+36
54x-43x= 36-14
11x = 22 /11
X =2
54*2+14 -= 122
Both the same
And the other are 180-122 = 58
Answer:
21.2 or 15 sqrt of 2 (PETHAGOREOM theorem)
Step-by-step explanation:
a^2+b^2=c^2
20^2+5^2=C^2
400+25=C^2
450=C^2
sqrt 450=
15 sqrt of 2 or 21.2
