Answer:
Step-by-step explanation:
If AD=DB and AE=EC,
then DE¯¯¯¯¯∥BC¯¯¯¯¯ and DE=12BC .
Since there are no actual values, I guess we just have to isolate the b.
2A=bh (multiply both sides by 2)
2A/h=b (divide by h)
hope this helps
Sin 30 = 1/2
tan 45 = 1
Cosec 60 = 2 / √3 = 2√3 / 3
cot 45 = 1
Cos 60 = 1/2
sec 30 = 2 / √3 = 2√3 / 3
_______________________________
[ 1/2 + 1 - 2√3/3 ] ÷ [ 1 + 1/2 - 2√3/3 ] = <em>1</em>
The face and denominator of the fraction are exactly the same thus the answer is 1 .
