Answer:
( z - 5 ) ( z - 5 )
Step-by-step explanation:
z² − 10z + 25
= z² − 5z - 5z + 25
= z ( z - 5 ) - 5 ( z - 5 )
= ( z - 5 ) ( z - 5 )
Oop- I’ll pass on telling you everything about me :/
Answer:
-
i
Step-by-step explanation:

i
Complementary angles add up to 90°
Let the unknown angle be 0..
0 + 42 = 90°
0= 90° - 42° = 48°
therefore, The complimentary angle of
42 is 48°
