Answer:
Step-by-step explanation:
Squaring a^(-2) results in a^(-4).
Squaring 8^7 results in 8^14.
Putting these factors together, we get
8^14
-------                     this is equivalent to Answer C.

Answer: The angle equals  45
∘  and the supplement is  135
∘
Explanation: 
Since the supplement is three times the angle, we can say    s  =  3
a
Since we know the supplement is  
180
−
a
, we can plug that in.
180 - a = 3a
180  =
4
a  (add  a  to both sides) 
45  =  a  (divide both sides by  4)
Since we know the angle now, all we have to do is multiply it times  3  to find the supplement.
45  ×  3  =  135
