One helpful tool in solving geometric proofs is to work backwards.
Looking at theorems related to the figure may also be helpful, to better
understand the proof and to check work. Finally, marking the figure to
reflect the given statements will help guide the person in determining
whether the proof is viable.
Answer:
10%
Step-by-step explanation:
40+5+5=50
50-5=45
45*2=90
50*2=100
100-90=10
Answer:
the top and bottom combined are 240 and one side is 1200, another side is 500 and another is 1250, so the surface area is 3190 cm
Step-by-step explanation:
It is simple !!
just find what ℅ is 18 of 90 !
so,
(18/90)×100 = 20 ℅ ....answer !!
