Answer 1

[tex]\angle A +\angle B+ \angle C+ \angle D=360^{\circ} \\ \angle A =\angle C~si~\angle B= \angle D~(opuse) \\ \angle A+ \angle B=180^{\circ}(ungh.~alatur.) \\ \angle C+ \angle D=180^{\circ}(ungh.~alatur.) \\ \angle A=35^{\circ} \\ ^{\underline{~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~}} \\ \angle B,\angle C,\angle D =??? \\ ^{\underline{~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~}} \\ \angle A=\underline{ \angle C=35^{\circ}} \\ 35+\angle B=180 \\ \underline{\angle B=\angle D=145^{\circ}}[/tex]
