S = 9C
first sentence written as an expression
Where S represents the angles supplement
and C represents the angles complement
A + S = 180
definition of supplementary allows me to make this statement Where A is the original angle
A + C = 90
definition of complimentary allows this statement
now add the prior 2 statements together
A + S + A + C = 180 + 90
now simplify
2A + S + C = 270
now replace S with 9C using first statement 
2A + 9C + C = 270
now simplify 
2A + 10C = 270
now divide both sides by 2
A + 5C = 135
now using the second statement isolate A by adding C to both sides
A = 90 - C
now combine the two prior statements
90 - C + 5C = 135
now simplify 
90 + 4C = 135
now subtract 90 from both sides
4C = 45
now divide both sides by 4
C = 11.25
so the complimentary angle is 11.25
now take the third equation and substitute in C
A + 11.25 = 90
now subtract 11.25 from both sides
A = 78.75
so the original angle is 78.75
now use the second equation and substitute in A
78.75 + S = 180
now subtract 78.75 from both sides
S = 101.25
so the suplimentary angle is 101.25
        
             
        
        
        
Substitute -1 for the variable x.
f(-1) = 2(-1) - 2
f(-1) = -2 - 2
f(-1) = -4
        
                    
             
        
        
        
SinB = 8/17
The sin of an angle is equal to opposite/hypotenuse 
Use Pythagorean’s Theorem to solve for the opposite side 

The opposite side is equal to 8
So sinB = 8/17
*look at attached photo for work
 
        
             
        
        
        
Sum of those two angles = 180 - 100 = 80
Now, Total ratio = 3 + 5 = 8
Amount of 1 unit = 80 / 8 = 10
Angle measures: = 3(10) & 5(10) = 30, 50
In short, Your Answer would be 30 & 50
Hope this helps!
