Which angle is supplemantary to eoa a. eod b. aob c. eoc d. aoc

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

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
