Answer:
6<em>i</em>
Step-by-step explanation:
sqrt(-121) - sqrt(-25)
11<em>i</em> - 5<em>i</em>
<u>6</u><u><em>i</em></u>
 
        
             
        
        
        
Since they are equal to 90 degrees. (complimentary angles)
6x-11+7x+10= 90
Combine like terms.
13x-1= 90
Add one to both sides.
13x= 91
x= 7
Plug that into the b.
7(7)+10
49+10
59
I hope this helps!
