סינוסים או קוסינוסים – איך לבחור פתרון – מדרגה 1

סינוסים או קוסינוסים – איך לבחור פתרון

מדרגה 1

הקודקודים $B$ ו- $C$ במשולש $ABC$ נמצאים על מעגל.

מרכז המעגל $O$ נמצא על הצלע $AB$ (ראו איור).

נתון: $AC=24 cm$ , $AO=8 cm$ , $\measuredangle BAC=60^{\circ}$

פתרו את הבעיות הבאות בשתי דרכים:

חשבו את רדיוס המעגל.
חשבו את אורך הצלע $BC$ .

תוכלו להיעזר ביישומון.

אחרי שפתרתם את הבעיות במדרגה 1, פתרו את בעיית המטרה.
או, במידת הצורך, פתרו את הבעיות במדרגה 2.

יישומון

בחירת הסעיף הנדרש מציגה רמזים לפתרון.
בחירת סעיף "המשך הפתרון" מציגה שתי אפשרויות לבחירה: שימוש במשפט הסינוסים או שימוש במשפט הקוסינוסים.
