Hello!
The variable "n" represents an exponent.
An exponent is used to multiply a number (b) by itself "n" times. For example, if the expression were to read (b²) it would represent the following:
b × b

b × b × b × b × b × b × b × b × b × b
I hope this helps!

Answer:
x is 70°
Step-by-step explanation:
80 + 55= 135
180-135 = 45
45 +45 =90
180-90=90
80+80= 160
180-160= 20
20 +90= 110
180-110 = 70
x is 70
