Answer:
Angle A = 18°
Step-by-step explanation:
since the angles are complementary, they add up to 90°
(2x-4) + (5x+17) = 90
add like terms
7x-4+17=90
simplify left side
7x+13=90
subtract 13 from both sides
7x=77
divide both sides by 7
x=11
plug in x to find the measure of angle A
2(11) - 4
multiply 2*11 first
22-4
simplify
18

Answer:
-1
Step-by-step explanation:
i^0 =1
i ^1 = i
i^2 =-1
i^3 = -i
It cycles through by 4
so i^4 is back to 1
Take the power , divide by 4 and look to the chart for the remainder
If the remainder is 0 then i to that power is 1
1 i
2 -1
3 -i
i^22
Take 22/4 = 5 remainder 2
The remainder is 2 so i^22 = -1
