A=12
120% of a =80% of b
120%a = 80%b
120a/100 = 80b/100
Divide through by 100
120a = 80b
Divide through by 80
120a/80 = b
But a=12
120x 12/80 = b
18 = b
b = 18
a+b = 12 + 18 = 30
First we'll multiply the second equation by -2
Now let's add the new equation and the first one.
We found y's value. We'll plug it in one of the equations to find x's value.
Solution ;
(9, -6)
Answer:
5π/6
Step-by-step explanation:
Subtract multiples of 2π until you find the angle in the desired range.
41π/6 -36π/6 = 5π/6
The angle 5π/6 is co-terminal with 41π/6.
I believe both answers are Shannon.
