Answer: 20 diagonales
Step-by-step explanation:
Answer:
x=13 y=10 z=3 d) 260
Step-by-step explanation:
vertex angles are congruent so you can set them equal to each other and solve
and then a straight like adds up to 180 so 180-(7(x-3)+5y)= your missing angle and then that angles is congruent to its opposite so 2(5z+15)=60
The answer would be 13/15
Answer:
155°
Step-by-step explanation:
I think that because when you imagine it
you feel like it's between 155° and 160°
but I think it's approximately to 155°.
