is the number of cups of flour to be mixed with water for making tortillas.
Relation between and
is given by the equation:
To find:
Number of cups of flour to be added if number of cups of water to be used is 1.
Solution:
We are given an equation with two variables.
Value of one variable is given and we have to find the value of other variable.

Answer:
The measure of arc a is 86°
Step-by-step explanation:
we know that
The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite.
so
86°=(1/2)[arc c+arc a]
see the attached figure with letters to better understand the problem
In this problem
Triangles ABO and CDO are congruent by SSS postulate theorem
∠AOB=∠COD
∠AOB=arc a -----> by central angle
∠COD=arc c -----> by central angle
therefore
The measure of arc a is congruent with the measure of arc c
arc a=arc c
so
86°=(1/2)[2arc a]
86°=[arc a]
arc a=86°
