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°
This statement is true because you multiply the exponents. 4 x 2 is equal to 8
Answer:
C
Step-by-step explanation:
dont know the 2nd :(
6:11 because polygons have 4 side so it would be 24:44 but it just reduces back to 6:11. hope this helped have a good day!!
