First, you know that the sum of all the angles is 540 degrees, so add them all together to find an equation that can be solved for b.
b+(3/2b)+(b-45)+(2b-90)+90=540
Then simplify the equation:
b+(3/2b)+b+2b=540+45+90-90
4b+(3/2b)=585
11/2b=585
11b=585x2
11b=1170
b=1170/11
b=106.36
Using this answer for 'b', you can plug it into the other values for the angles to find the final answers.
Answer:
(0,5) (1/2, -1) (1, 3)
Step-by-step explanation:
We basically plug in all of these points.
(0,0) --> 0=8(0)-5 <-- This is not true, because 0 ≠ -5
(0,5) --> -5=8(0)-5 <-- This is true, because -5 = -5
(1/2, -1) --> -1=8(1/2)-5 <-- This is true because -1 = -1
(8, -5) --> -5=8(8)-5 <-- This is not true because -5 ≠ 59
(1, 3) --> 3=8(1)-5 <-- This is true because 3 = 3
