(3+3i) - (13+15i)
=3+3i-13-15i
=-10-12i
Answer:
∠EFG = 48°
Step-by-step explanation:
As FH bisects ∠EFG , ∠EFH = ∠HFG .
We know that ∠EFH = (-5x + 89)° . So ∠HFG = ∠EFH = (-5x + 89)°
Also, ∠HFG + ∠EFH = ∠EFG
=> 2(-5x + 89)° = (61 - x)°
=> -10x + 178 = 61 - x
=> 10x - x = 178 - 61
=> 9x = 117
=> x = 117 / 9 = 13
Putting the value of 'x' in ∠EFG gives :-
(61 - x)° = (61 - 13)° = 48°

what is b? from the first equation in the system, y + 2 = b.
Answer:
7. is 2 squared. I didn't show my work but I am very sure that's the answer.
20% because 9 divided by 45 is 0.2 which is 20%
