Here, You need to apply "Proportionality Theorem"
According to this theorem, the ratio of components of a leg would be equal to the ratio of corresponding components of another leg.
In mathematical form,
AB/BD = AC/CD
Substitute their values,
36/24 = x/18
2/3 = x/18
x = 18*3 / 2
x = 54 / 2
x = 27
In short, Your Answer would be 27
Hope this helps!
Seed mix a is more expensive than b
-9/4 - 4i is your answer. B
Lets O is the center of the circle and Lets A is a point cut on CD from O
mCD = m<COD
OA is perpendicular bisector of CD so OA = 1/2 CD = 1/2(12.7) = 6.35
Sin (DOA) = AD/OD = 6.35 / 9.06
Sin DOA = 0.7009
<DOA = 44.5°
<COD = 2 x 44.5°
<COD = 89°
mCD = <COD = 89°
Answer: 89°
