Huu hapa ni ufumbuzi wa swali lako:

Tafuta thamani ya aa na bb

  1. Tambua sifa za pembe tatu MNOMNO.

    Kutoka kwenye mchoro, tunaona alama za vema kwenye pande MNMN na NONO. Hii inamaanisha kuwa MN=NOMN = NO, hivyo pembe tatu MNOMNO ni pembe tatu pacha (isosceles triangle). Katika pembe tatu pacha, pembe zinazokabili pande sawa ni sawa.
    Hivyo, ∠MON=∠M\angle MON = \angle M.
    Tunapewa ∠M=56∘\angle M = 56^\circ.
    Kwa hiyo, ∠MON=56∘\angle MON = 56^\circ.

  2. Tafuta thamani ya aa.

    Jumla ya pembe za ndani za pembe tatu ni 180∘180^\circ. Katika pembe tatu MNOMNO:

    ∠M+∠MON+∠N=180∘\angle M + \angle MON + \angle N = 180^\circ 56∘+56∘+a=180∘56^\circ + 56^\circ + a = 180^\circ 112∘+a=180∘112^\circ + a = 180^\circ a=180∘−112∘a = 180^\circ - 112^\circ a=68∘a = 68^\circ

    Thamani ya aa ni 68∘\boxed{\text{68}^\circ}.

  3. Tafuta thamani ya bb.

    Mstari MQMQ ni mstari ulionyooka. Pembe kwenye mstari ulionyooka hujumlisha 180∘180^\circ.
    Pembe bb na ∠MON\angle MON ziko kwenye mstari ulionyooka MQMQ.
    Hivyo, ∠MON+b=180∘\angle MON + b = 180^\circ.

    56∘+b=180∘56^\circ + b = 180^\circ b=180∘−56∘b = 180^\circ - 56^\circ b=124∘b = 124^\circ

    Thamani ya bb ni 124∘\boxed{\text{124}^\circ}.

    Kumbuka: Pembe ya 19∘19^\circ haihitajiki kutafuta thamani za aa na bb kama zilivyoelezwa kwenye mchoro.
