Answer:
c=28
Step-by-step explanation:
In a convex polygon, all the exterior angles are congruent to each other.
I'll be choosing the two angle degrees of 4c-28 and 3c and set them equal to each other.
4c-28=3c
Therefore, c=28
Step-by-step explanation:
To find the formula for the nth term ,
First , find the common difference or common ratio.
Common difference =

Common ratio =

The common difference applies to the other given numbers for example :

this proves that it is an arithmetic sequence and the given formula for the nth term of an arithmetic sequence is
T_n =a(n-1)d
Where n = no of terms
a= first term
d= common difference
Answer: 129
Step-by-step explanation:
It is 129 because y is less than 70 so the greatest possible value for that is 69 and z is less than or equal to 60 so 69 + 60 =129
The compass heading is 242.5deg
