    Radius of circle = 50/2 = 25 cm

     

    perpendicular distance = 24 cm

     

     

     

    Therefore, By Pythagoras theorem:

     

    Hypotenuse² = Base² + Perpendicular ²

     

    25² = Base² + 24²

     

    Base² = 625 - 576

     

    Base² = 49

     

    Base = 7

     

     

    Chord = 2 × Base

     

    Chord = 2 × 7

     

    Answer: 14 cm

    Formula for the probability of A and B (independent events): p(A and B) = p(A) * p(B). If the probability of one event doesn't affect the other, you have an independent event. All you do is multiply the probability of one by the probability of another.

    SSS (Side-Side-Side)

    If all the three sides of one triangle are equivalent to the corresponding three sides of the second triangle, then the two triangles are said to be congruent by SSS rule.

    In the diagrams below, if AB = RP, BC = PQ and CA = QR, then triangle ABC is congruent to triangle RPQ.

    It is given that, ∠Q = 2∠PRQ. In ΔPQR, ∠PQR + ∠PRQ + ∠RPQ = 180° ⇒ 2∠PRQ + ∠PRQ + 90° = 180° ⇒ 3∠PRQ = 180° − 90° = 90° ⇒ ∠PRQ = 90°/30=30° … (1) ∴ ∠PQR = 2 × 30° = 60° … (2) Now, extending QP to S such that QP = PS, and joining RS. P /|\ / | \ / | \ / | \ / | \ / | \ / | \ / | \ / | 90° \ /______ |__________\ S Q R In ΔRPQ and ΔRPS: RP = RP (Common) ∠RPQ = ∠RPS = 90° PQ = PS (by construction) ∴ ΔRPQ ≅ ΔRPS (by SAS congruence rule) ⇒ RQ = RS and ∠PRQ = ∠PRS (CPCT) Now, ∠SRQ = ∠PRQ + ∠PRS = 2∠PRQ = 2 × 30° = 60° [from (1)] By CPCT, we obtain ∠PQR = ∠PSR ∴ ∠PSR = 60° [from (2)] Therefore, ΔQRS is an equilateral triangle. ⇒ QR = RS = SP = 10 cm ∴ SP = PQ = 10cm/2=5cm On applying Pythagoras theorem to ΔPQR, we obtain RP2 + PQ2 = QR2 ⇒ RP2 + (5 cm)2 = (10 cm)2 ⇒ RP2 + 25 cm2 = 100 cm2 ⇒ RP2 = 75 cm2 ⇒ RP =5√3cm ∴ Perimeter of ΔPQR = RP + PQ + QR =(5√3+5+10)cm = (5 × 1.73 + 15) cm = 23.65 cm Thus, the perimeter of ΔPQR is 23.65 cm. The correct answer is C.

    Given :

     

    In a triangle ABC :

     

    ∠ A -  ∠ B = 33

     

    ∠ B  -  ∠ C = 18

     

    We have find values of all angle :

     

    We know sum of all interior angle of triangle is 180 .

     

    ∠ A + ∠ B + ∠ C = 180 .. ( ii )

     

    We have :

     

    ∠ A -  ∠ B = 33

     

    ∠ B  -  ∠ C = 18

     

    Rewrite as :

     

    ∠ A  = 33 + ∠ B

     

    ∠ C = ∠ B - 18

     

    Now putting

     

    33 + ∠ B + ∠ B + ∠ B - 18 = 180

     

    3 ∠ B + 15 = 180

     

    3 ∠ B = 165

     

    ∠ B = 55

     

    Putting values of B in :

     

    ∠ A -  ∠ B = 33

     

    ∠ B  -  ∠ C = 18

     

    ∠ A = 88

     

    ∠ C = 37 .

     

    Answer:

     

    ∠ A = 88

     

    ∠ B = 55

     

    ∠ C = 37 .

    Trapezium:

    1. Like other quadrilaterals, the sum of all the four angles of the trapezium is equal to 360°
    2. A trapezium has two parallel sides and two non-parallel sides
    3. The diagonals of regular trapezium bisect each other
    4. The length of the mid-segment is equal to half the sum of the parallel bases, in a trapezium
    5. Two pairs of adjacent angles of a trapezium formed between the parallel sides and one of the non-parallel side, add up to 180 degrees.

    Rhombus:

    • All sides of the rhombus are equal.
    • The opposite sides of a rhombus are parallel.
    • Opposite angles of a rhombus are equal.
    • In a rhombus, diagonals bisect each other at right angles.
    • Diagonals bisect the angles of a rhombus.

     

    Parallelogram:

    • The opposite sides are congruent.
    • The opposite angles are congruent.
    • The consecutive angles are supplementary.
    • If anyone of the angles is a right angle, then all the other angles will be the right angle.
    • The two diagonals bisect each other.
    • Each diagonal bisects the parallelogram into two congruent triangles.
