Question

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

Answer 1

<EOC = <DOE + <DOC
5x - 3 = 2x + 9 + 93
5x - 2x = 3 + 9 + 93
3x = 105
x = 105 : 3
x = 35

Sudut EOC =
5x - 3
5(35) - 3
175 - 3
172 derajat

Sudut EOA + Sudut COB =
180 - sudut EOC
180 - 172
8 derajat

Answer 2

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
