What you have presented is called a cyclic quadrilateral. A cyclic quadrilateral is a 4 sided figure whose angles (4 of them) all touch the circumference of a circle.
Here's what you want to know. Two angles that are opposite each other are supplementary (they add to 180 degrees)
Equation
x + 80 = 180 Subtract 80 from both sides.
Solution
x + 80 - 80 = 180 - 80 Combine
x = 100
Answer
x = 100
It's asking for the "perimeter" of the molding as far as I can tell,
namely, how long is the border of that molding

Answer:
-1 is the inverse of 16 modulo 17.
Step-by-step explanation:
To find : An inverse of 16 modulo 17 i.e.
?
Solution :
First we find the GCD of (17,16) using Euclid's algorithm,

Remainder is 1.
Which means, GCD(17,16)=1
Using back substitution we get,



i.e. -1 is the inverse of 16 modulo 17.
On comparing with 
The value of x=-1.
