You would need to write a solvable equation, and you can do this because you know that angles in a triangle add up 180° so the missing angle must be (180 - 9x). This makes the equation:
5x + 9 + x + (180 - 9x) = 180
6x + 9 + 180 - 9x = 180
-3x + 189 = 180
- 189
-3x = -9
÷ -3
x = 3
So your answer is x = 3, I hope this helps!

You divide 19.6 by 4
Answer:
8.16 Kg
Step-by-step explanation:
average is calculated as
average = 
here average = 0.17 and count = 48 , then
0.17 = 
( multiply both sides by 48 )
8.16 = sum
that is total mass = 8.16 Kg
Answer:
no
Step-by-step explanation:
he starts with 90 bucks to find what the fraction represents you can multiply it by 2 to get an equal denominator of 90 then subtract 90-62 that'll give you 28 then it says he spent 3/7 so you do the same thing get an equal denominator by multiplying by 4 and get 28 and as they say whatever you do to the denominator is done to the numerator so 3 times 4 is 12 then you do 28-12 and you gets 16 which isn't enough to buy the hat. :)
The supplementary angle is 0.628.
Hope that helps
