    6. Kutatua pembetatu, rounding kwa karibu kumi, kuchukua\(\alpha\) ni kinyume upande\(a, \beta\) ni kinyume upande\(\mathbf{b},\) na\(\gamma\) s upande kinyume\(c: a=4, \quad \mathbf{b}=6, c=8\)

    7. Tatua pembetatu kwenye Mchoro wa 2, ukizunguka hadi kumi ya karibu.

    Pembetatu iliyoandikwa kwa kawaida. Angle A ni 54 digrii na upande kinyume haijulikani. Angle B haijulikani kwa upande kinyume b=15. Angle C haijulikani kwa upande kinyume C=13.

    8. Pata eneo la pembetatu na pande za urefu\(8.3,6.6,\) na 9.1.

    9. Ili kupata umbali kati ya miji miwili, satellite huhesabu umbali na angle iliyoonyeshwa kwenye Mchoro 3 (sio kiwango). Pata umbali kati ya miji. Majibu ya pande zote kwa kumi ya karibu.

    Mchoro wa satellite hapo juu na haki ya miji miwili. Umbali kutoka satelaiti hadi mji wa karibu ni 210 km. Umbali kutoka satelaiti hadi mji zaidi ni 250 km. Pembe iliyoundwa na mji wa karibu, satellite, na mji mwingine ni digrii 1.8.
