since the triangles are similar
angle DEC = 60 degrees
3 angles inside a triangle equal 180 degrees
BAC = DCE = 64
CBA = EDC = 56
DEC = 180 -56 -64 = 60 degrees
used angle-angle theorem
1. 1m=100 cm
1m^2= 10,000 cm^2
2. if 3 pencils are 1.65, then 1 pencil is 1.65/3=$ 0.55
7 pencils will cost 7* $0.55= $3.85
3.1 ha is 10,000 m^2, and 1 soccer filed is roughly 100m *110 m
so it makes sense that 1 ha is roughly 2 tennis courts
4.odd numbers between 20 and 30 are
21,23,25,27,29
lets add the,m
21+23+25+27+29=125
5 a rhombus has 2 lines of symmetry
Answer:
answer is 3ZSM 1
Step-by-step explanation:
it has a Brainly question for something experimentable:-)
Answer:
They payed $45
Step-by-step explanation:
