Felicia wants to build a kite with the shape shown. If AC is 60 cm, how many centimeters are in the length of BD?
Kay [80]

Answer:

Step-by-step explanation:

By applying tangent rule in the given right triangle AOB,

tan(30°) = \frac{\text{Opposite side}}{\text{Adjacent side}}

\frac{1}{\sqrt{3}}=\frac{BO}{OA}

OA=BO(\sqrt{3})

By applying tangent rule in the given right triangle BOC,

tan(60°) = \frac{OC}{BO}

OC = BO(√3)

OA + OC = AC

BO(\sqrt{3})+BO(\sqrt{3}) =60

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°) = \frac{OD}{OC}

OD = OC(√3)

OD = 30√3

Since, BD = BO + OD

BD = 10√3 + 30√3

BD = 40√3

      ≈ 69.3

There are five candies in a bag. Three are chewy, and two are chocolate. You draw a candy, do not replace it, and then draw anot
castortr0y [4]

It has been computed that the probability of choosing two chocolate candies is 2/25.

<h3>How to calculate probability</h3>

The probability of choosing the first chocolate candy will be 2/5.

The probability of choosing the second chocolate candy will be 1/5.

Therefore, the probability of choosing two chocolate candies will be:

= 2/5 × 1/5

= 2/25
