3x(8r-1) x (4r+2s)
3x7r x (4r+2s)
21r x (4r+2s)
Answer:4.265
Step-by-step explanation:
Can it be decimal?
The complete question in the attached figure
we know that
<span>The measure of the external angle is the semidifference of the arcs that it covers.
so
</span><span>m∠BED =(1/2)*[mAC-mBD]-------> solve for mBD
mBD=mAC-2</span>m∠BED
mBD=80-2*25--------> mBD=30°
the answer ismBD=30°

I thought this would be easy lol, I tried, sorry for not getting an answer
P = 2L + 2W ....subtract 2L from both sides
P - 2L = 2W ...divide both sides by 2
(P - 2L) / 2 = W .....can also be written like (P/2) - L = W
