Answer:
8
Step-by-step explanation:
Considering the given value of sum of interior angles with exclusion of one to be 1070 then we can write it as
1070=180(n-2) where n is the number of sides required here.
Making n the subject of the formula then following step by step


Therefore, the shape is octagon and it has 8 sides.
Answer:
45.50° F
Step-by-step explanation:
As per Newton's law,

When T(t) is the final temperature
= Temperature of surrounding
= Initial temperature
t =duration of cooling
k = constant


Now take natural log on both the sides



4.6347 - 5.0434 = -5k

k = 0.0817

= 
= 155 (02935)
= 45.49 ≈ 45.50° F
