Question

DAU 13 PUNTE + COROANA + RASPUNS LA O INTREBARE !! URGENT !!

Answer 1

10. figura a: DOA+AOB=180°
AOB=47° => DOA=133°
=> DOC=47°; COB=133°
figura b: QOM+MON=180 => 3x+x=180
4x=180
x=45°
=>QOM=45×3=135°; MON=45°; NOP=135°; POQ=45°
figura c: EAB+BAC=180 => x+120°+x=180°
2x=60°
x=30°
=>EAB=120°+30°=150°; BAC=30° ; CAD=150°; DAE=30°
11. figura a: DMC+CMB=180° => DMC=150°
DMC+EMD=180° => EMD=30°
EMA+AMC=180° => EMA=90°
AMB+CMB=90° => AMB=60°
figura b: ROQ+QOP=90° => QOP=20°
QOR+ROM=180° => ROM=110°
ROM+MON=180° => MON=70°
figura c: UOT+TOZ+ZOY=180° => x+2x+3x=180°
6x=180°
x=30°
=>UOT=30°; TOZ=60°; ZOY=90°
TOU+UOX=180° => UOX=150°
UOX+XOY=180° => XOY=30°
figura d: x+x+10°+5x+30°=180° ; 7x=140°
x=20°
=>BAC=20°; CAD= 30°; DAE=130°
FAE+EAD=180°=> FAE=50°
BAF+FAE=180°=>BAF=130°
