MN is a diameter of a circle with centre ' O ' . If BD = CD , prove that ∠OAD = ∠OCD
Varvara68 [4.7K]

Answer:

\sf \: Proved \: \angle \: OAD  \:  =  \angle \: OCD

Step-by-step explanation:

<em>Given:</em>

Mn is diameter of circle having centre O

and BD = OD,

<em><u>To prove that:</u></em>

<u>\angle \: OAD  \:  =  \angle \: OCD</u>

<em>Solution:</em>

Join the points O and B and draw OB,

On joining the line,

in ∆OCD and ∆OBD,

OC =OB → (Radius of same circle)

BD =CD → (from given)

OD =OD → (Common side in both the triangles)

Hence ∆OCD and ∆OBD are congruent from SSS property.

so we can say that,

\angle \: OBD  \:  =  \angle \: OCD

Consider above prove as statement A

Corresponding angles of congruent traingle.

in ∆ OAB,

OA = OB (radius of same circle)

hence ∆OAB is an isosceles traingle.

We know that opposite angle of isosceles traingle are always equal. hence,

\angle \: OBD  \:  =  \angle \: OAB \\ \angle \: OAB  \:  =  \angle \: OAD (same \: angles) \\ \angle \: OBD  \:  =  \angle \: OAD

Consider above prove as statement B

From Statement A & B we can say that

\angle \: OAD  \:  =  \angle \: OCD

The data set below represents the total number of home runs that a baseball player hit each season for 11 seasons of play. What
goblinko [34]

Answer:

The interquartile range of the data is 12

Step-by-step explanation:

Data : 14, 22, 19, 21, 30, 32, 25, 15, 16, 27, 28 12 16 22 28

Data in ascending order : 12 ,14 ,15 ,16 ,16 ,19 ,21 ,22 ,22 ,25 ,27 ,28 ,28 ,30 ,32

Lower quartile :12 ,14 ,15 ,16 ,16 ,19 ,21

Q1 is the median of lower quartile

n = 7

Median =\frac{n+1}{2} \text{th term}=\frac{7+1}{2}=4 \text{th term}=16

Upper quartile :22 ,25 ,27 ,28 ,28 ,30 ,32

Q3 is the median of upper quartile

n = 7

Median =\frac{n+1}{2} \text{th term}=\frac{7+1}{2}=4 \text{th term}=28

IQR = Q3-Q1=28-16= 12

Hence the interquartile range of the data is 12
