Hi bestie ily I hope you find the answers ♀️
Let the first angle be A and the second be B.
Complementary angles add up to 90° so:
A + B = 90
We are also told:
A = 6 + 3B; substituting this into the first equation:
6 + 3B + B = 90
B = 21°
A = 6 + 3(21)
A = 69°
Answer:
n = 3
Step-by-step explanation:
-18 = -6n - 6 + 2n
-18 = -6n +2n -6 (Combine like terms)
-18= -4n -6
-18+6= -4n -6+6 (Addition Property of Equality)
-12 = -4n
-12/-4 = -4n/-4 (Division Property of Equality)
3=n
The value of 'n' is 3.
