Hello!!!
Let'sworkoutwiththisfigure.
BCisachord,OisthecentreandOAistheperpendicularbisector.
AB=1/2ofBC(accordingtocircle'stheorem)
so,AB=1/2×25.6
Therefore, themeasureofABis12.8.
now,let'shaveasmallworkwithtriangleAOB.
asitisaRight angled triangle, takingangleBasrefrenceangleweget,
p=x
b=12.8
h=OB=16(itisalsoaradius.)
now,
byPythagorasrelationwe get,
or,x=root16^2-12.8^2
bysimplification, weget;
themeasureofxis9.6.
Therefore, thevalueofxis9.6.
Hope it helps...
4 sin^2 x - 4 sin x + 1 = 0
Answer:
Answer:
D) a = 14, b = 6√2
Step-by-step explanation:
The given figure is trapezoid.
When we draw perpendicular to base "a", we get h = 6
From 45, 45, 90 degrees triangle, the ratio of sides 1:1:√2
since h = 6, b = 6√2
a = 8 + 6
a= 14
Therefore, a = 14 and b = 6√2
Thank you.
