Step-by-step explanation:
By applying tangent rule in the given right triangle AOB,
tan(30°) =
By applying tangent rule in the given right triangle BOC,
tan(60°) =
OC = BO(√3)
OA + OC = AC
2√3(BO) = 60
BO = 10√3
OC = BO(√3)
OC = (10√3)(√3)
OC = 30
By applying tangent rule in right triangle DOC,
tan(60°) =
OD = OC(√3)
OD = 30√3
Since, BD = BO + OD
BD = 10√3 + 30√3
BD = 40√3
≈ 69.3
A principle square root of a real number that's not negative, such as 49, is the square root of that number that is not negative.
If you take the square root of 49, you get either -7 or 7, since both
and 
equal 49. However, the principle square root would be A) 7, since it's not negative.
If you take the square root of 49, you get either -7 or 7, since both
