Question

Bantu jawab ,bsok dikumpull!!!!beserta caranya yg no 2,4,5 ajaaaaaaaaa!!!!#thx. yg sudut DOC 93drjt

Answer 1

2) ∠EOC=∠DOC+∠DOE
5x-3=93+2x+9
5x-2x=93+9+3
3x=105
x=35

∠EOC=5(35)-3=172
∠DOE=2(35)+9=79

∠EOA+∠COB=180-172=8

4)∠B1=90
∠B2=∠A3=180-(90+50)=40
∠B3=180-(90+40)=50

5)Q=125
S=115
T=125
U=115
V=180-125=55
W=180-115=65
