Answer:
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
Answer:
-233/40
Step-by-step explanation:
5/8 + 1/4 - 2(3/4 + 13/5)
5/8 + 2/8 - 6/4 + 26/5
7/8 - 30/20 + 104/20
7/8 - 134/20
35/40 - 268/40
-233/40
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

(83 + x)/2 = 107
83 + x = 107 * 2
83 + x = 214
x = 214 - 83
x = 131°
