Answer:
See explanation
Step-by-step explanation:
In quadrilateral BADC,
AB= AD
BC= DC
AC is a line of symmetry for this quadrilateral
Consider triangles BAC and DAC. In these triangles,
- AB = AD - given
- BC = DC - given
- AC = AC - reflexive property
So, ΔBAC ≅ ΔDAC by SSS postulate.
Congruent triangles have congruent corresponding sides and angles, so
m∠ACB = m∠ACD
<u>Another way:</u> The line of symmetry can be defined as the line that divides the figure into two identical figures. Thus, ΔBAC and ΔDAC are identical (congruent) and have congruent corresponding sides and angles.
Answer:
Mira washo lo que tienes que hacer para que tener el resultado debes poner tu regla en los lados y en su longitud para que asi tengas el resultado obio no tienes que multiplicar ni hacer nada de eso solo tienes que medir su longitud y su altura xque veo y su altura es de 75cm y adentro tiene un 17 cqe supongo que es la longitud .v. entonces nose .v."

Answer:
B) x=80°
Step-by-step explanation:
This is a hexagon, so it has interior angles equaling 720°. (N-2)*180
So the equation would be
78+134+136+132+2x+x=720
480+3x=720
3x=720-480
3x=240
x=80°
