Solution

user avatar imageAnswerp = 4.232 \;cmExplanationDetail steps\sin A=\dfrac{leg\;opposite\;\angle{A}}{hypotenuse}: \sin{\left(\angle {ACB} \right)} = \dfrac{\overline {AB}}{\overline {AC}}Substitute \overline {AB} = p , \overline {AC} = 7.2\;cm , \angle {ACB} = 36^{\circ} into \sin{\left(\angle {ACB} \right)} = \dfrac{\overline {AB}}{\overline {AC}}: \sin{\left(36^{\circ} \right)} = \dfrac{p}{7.2}Calculate \sin{\left(36^{\circ} \right)} = \dfrac{p}{7.2}: p = 4.232\;cmClick to rate:21.6(74 votes)Search questionBy textBy image/screenshotDrop your file here orClick Hereto upload
