Respuesta :

Supplementary angles are angles which add up to 180°. ∠EOA is a right angle, the measurement of ∠EOA is 90°. That means it needs another right angle to add up to 180°. Another right angle which is adjacent to ∠EOA is ∠EOC. Therefore, ∠EOA and ∠EOC are suppleentary.

ANSWER: C. 
EOC

Answer:

option C

Step-by-step explanation:

From the given figure, angle EOA is right angle so the measurement of <EOA is 90 degree

Supplementary angles are linear pair. Supplementary angles are in a straight line.

< EOA  and < EOC are linear pair. they make a straight line

So <EOC is supplement to <EOA

Answer is option C
