Answer» Answer: x ∈ (-2, 7) Step-by-step explanation: ★ x ∈ (-2, 7) means that the value of x lies between -2 to 7 excluding -2 and 7. ★ So, we represent them in the form of open interval by using Normal brackets. ★ The possible values of x can be any of these numbers: → {-1, 0, 1, 2, 3, 4, 5, 6} x ∈ (-2, 7] means that the value of x lies between -2 to 7 including 7 but excluding -2. The set is defined as: {x : x ∈ R, -2 < x ≤ 7} *Similarly,* x ∈ [-2, 7] means that x lies between -2 to 7 including both -2 and 7 The set is defined as: {x : x ∈ R, -2 ≤ x ≤ 7}

The set {X:XER, -2 < X < 7 } can be written as

Answer»

Answer:

x ∈ (-2, 7)

Step-by-step explanation:

★ x ∈ (-2, 7) means that the value of x lies between -2 to 7 excluding -2 and 7.

★ So, we represent them in the form of open interval by using Normal brackets.

★ The possible values of x can be any of these numbers:

→ {-1, 0, 1, 2, 3, 4, 5, 6}

x ∈ (-2, 7] means that the value of x lies between -2 to 7 including 7 but excluding -2.

The set is defined as: {x : x ∈ R, -2 < x ≤ 7}

Similarly,

x ∈ [-2, 7] means that x lies between -2 to 7 including both -2 and 7

The set is defined as: {x : x ∈ R, -2 ≤ x ≤ 7}

Answer» Answer: It is given that AB is a DIAMETER of a circle with centre O and DO \|\| CB (i) We know that ABCD is a cyclic quadrilateral It can be written as ∠BCD + ∠BAD = 180o By substituting the values 120o + ∠BAD = 180o On further calculation ∠BAD = 180o – 120o By subtraction ∠BAD = 60o (ii) We know that the angle in a semi-circle is RIGHT angle ∠BDA = 90o Consider △ ABD By using the angle sum property ∠BDA + ∠BAD + ∠ABD = 180o By substituting the values 90o + 60o + ∠ABD = 180o On further calculation ∠ABD = 180o – 90o – 60o By subtraction ∠ABD = 180o – 150o So we GET ∠ABD = 30O (iii) We know that OD = OA So we get ∠ODA = ∠OAD = ∠BAD = 60o From the figure we know that ∠ODB + ∠ODA = 90o By substituting the values ∠ODB + 60o = 90o On further calculation ∠ODB = 90o – 60o By subtraction ∠ODB = 30o It is given that DO \|\| CB We know that the alternate angles are equal ∠CDB = ∠ODB = 30o (iv) From the figure we know that ∠ADC = ∠ADB + ∠CDB By substituting the values ∠ADC = 90o + 30o By addition ∠ADC = 120o Consider △ AOD By using the angle sum property ∠ODA + ∠OAD + ∠AOD = 180o By substituting the values 60o + 60o + ∠AOD = 180o On further calculation ∠AOD = 180o – 60o – 60o By subtraction ∠AOD = 180o – 120o So we get ∠AOD = 60o We know that all the angles of the △ AOD is 60o Therefore, it is proved that △ AOD is an equilateral triangle.

In given figure, BAC = 60° and AB is a diameter, then CBD is:

Answer»

Answer:

It is given that AB is a DIAMETER of a circle with centre O and DO || CB

(i) We know that ABCD is a cyclic quadrilateral

It can be written as

∠BCD + ∠BAD = 180o

By substituting the values

120o + ∠BAD = 180o

On further calculation

∠BAD = 180o – 120o

By subtraction

∠BAD = 60o

(ii) We know that the angle in a semi-circle is RIGHT angle

∠BDA = 90o

Consider △ ABD

By using the angle sum property

∠BDA + ∠BAD + ∠ABD = 180o

By substituting the values

90o + 60o + ∠ABD = 180o

On further calculation

∠ABD = 180o – 90o – 60o

By subtraction

∠ABD = 180o – 150o

So we GET

∠ABD = 30O

(iii) We know that OD = OA

So we get ∠ODA = ∠OAD = ∠BAD = 60o

From the figure we know that

∠ODB + ∠ODA = 90o

By substituting the values

∠ODB + 60o = 90o

On further calculation

∠ODB = 90o – 60o

By subtraction

∠ODB = 30o

It is given that DO || CB

We know that the alternate angles are equal

∠CDB = ∠ODB = 30o

(iv) From the figure we know that

∠ADC = ∠ADB + ∠CDB

By substituting the values

∠ADC = 90o + 30o

By addition

∠ADC = 120o

Consider △ AOD

By using the angle sum property

∠ODA + ∠OAD + ∠AOD = 180o

By substituting the values

60o + 60o + ∠AOD = 180o

On further calculation

∠AOD = 180o – 60o – 60o

By subtraction

∠AOD = 180o – 120o

So we get

∠AOD = 60o

We know that all the angles of the △ AOD is 60o

Therefore, it is proved that △ AOD is an equilateral triangle.
