    2^4(1 – x) + 2x = 2^7x + 1
    4(1 – x) + 2x = 7x + 1
    4 – 4x + 2x = 7x + 1

    Obtuse Reflex
    <MOP + <MOP = 360(angle at a point)
    Obtuse <MOP + 196° = 360°
    Obtuse <MOP = 360 - 196
    = 164°

    OMP + OPM + Obtuse MOP = 180°(<s in a triangle)
    But OMP = OPM = x(radius of the circle and hence base angles are the same)

    2x + 164 = 180
    2x = 180 - 164
    2x = 16°
    X = 16/2 = 8°

    Also MNP = 1/2×obtuseMOP

    = 82°

    Now; MNP + NMP + NPM = 180° (<s in a triangle)
    82 + (52+8) + (m+8) = 180°
    m + 150 = 180°

    AOM = 180 - 130 = 50°

    Also;
    BMO = BAO + AOM(Ext < = sum of two opposite interior <s of a triangle)
    BMO = 26 + 50 = 76°
    Also; ABD = 1/2AOD(angle at centre = twice angle at circum)
    ABD = 1/2 × 130

    Hence ODB + ABD + BMO = 180°(sum of <s in a triangle)

    Given: Im = 20×10^-3A; V = 25sin100πl
    Capacitive reactance Xl = Vm/Im = 25/26×10^-3 = 1250ohms

    (11dii)
    1/2πfc = Xl
    Where f = 50Hz
    1/2×22/7×50c = 1250
    314.286c × 1250 = 1
    392857 c = 1
    C = 1/392857 = 2.545×10^-6F
    = 2.545uf

    Low voltage battery : Used to heat the heater or heating element

    (12bii)
    target metal : Used to collect the emitted electrons

    α - particle has a Helium nuclei He while a β-particle has high energy electrons

    (12cii)
    α-particle has a charge at +2e while β-particle has a charge of -e

    Given 238 U --> m X + 2α
    92 n
    = 238 U --> m X + 2 4He
    92 n 2
    m+(2×4) = 238
    m + 8 = 238
    m = 238 - 8 = 230
    Also
    N + (2×2) = 92
    N + 4 = 92
    N = 92 - 4
    n = 88

    No of neutrons = 230 - 88 = 142
    Neutron - Proton ratio = 142/88 = 1.61
