Answer:
14
Step-by-step explanation:
A number that is exactly halfway between 1 and 27 is the middle number
In other words, we want to find the median between 1 and 27
Median = (x + y) / 2
Let
x = 1
y = 27
Median = (x + y) / 2
= (1 + 27) / 2
= 28/2
= 14
Therefore, the number between 1 and 27 is 14

Answer:
6.1° and 83.9°
Step-by-step explanation:
Complementary angles sum 90°
a+b = 90°
a = b - 77.8
then:
(b - 77.8) + b = 90
2b - 77.8 = 90
2b = 90 + 77.8
2b = 167.8
b = 167.8/2
b = 83.9°
a = b - 77.8
a = 83.9 - 77.8
a = 6.1°
