X+y=11
xy=128
x=11-y, so (11-y)y=128
11y-y²=128
y²-11y+128=0
use the quadratic formula to find y: y=(11+√391i)/2 or y= (11-√391i)/2
x=(11-√391i)/2, or x=(11+√391i)/2
so either there is an error in your question, or you have two unreal numbers:
(11-√391i)/2 and (11+√391i)/2
Answer:
(C) α + β + γ
Step-by-step explanation:
The sum of interior angles of ΔOCB & ΔOCA = 180° x 2 = 360°
α + β + γ + (360°-x) = 360°
x = α + β + γ
I think your answer is 125 cm. Good Luck.
Answer:
Basically you add all the numbers shown there and divide by how many there are. So you just get the sum and divide that by 11 since there are 11 numbers. Happy to help! (mean)
