Haya hapa masuluhisho ya swali ulilotuma:
Qn 18: Katika mchoro ufuatao, tafuta thamani ya .
Mchoro: Mchoro unaonyesha duara yenye kituo O. AB ni tangent kwa duara kwenye B, na urefu wake ni 15 cm. OB ni radius ya duara, na urefu wake ni 8 cm. Mstari AO unapita katikati ya duara, na sehemu ya mstari kutoka A hadi sehemu ya kwanza ya duara (wacha tuiite C) imeandikwa .
Step 1: Tambua pembetatu ya kulia na tumia theorem ya Pythagoras. Radius OB ni perpendicular kwa tangent AB kwenye sehemu ya kugusa B. Hivyo, ni pembetatu ya kulia na . Tunajua: • OB (radius) = • AB (tangent) = Tunahitaji kupata urefu wa hypotenuse OA.
Step 2: Kokotoa urefu wa OA.
Step 3: Tumia urefu wa OA na radius kupata . Mstari AO unapita katikati ya duara. Sehemu ya mstari kutoka O hadi kwenye duara (OC) ni radius. Hivyo, OC = . Kutoka kwenye mchoro, tunaona kwamba OA ni jumla ya AC na OC. Tunajua OA = , AC = , na OC = .
Step 4: Tatua kwa . Thamani ya ni .
