Question

Right triangle WXY is similar to triangle DEF. The following are measurements in right triangle DEF: mZF= 90° DE = 1113 DF = 7 EF = 8 What is the value of cos W? sin W7 tan W?

Answer 1

`\cos \text{ W = }\frac{7}{\sqrt[]{113}}\text{ = }\frac{7\sqrt[]{113}}{113}`
`\sin \text{ W = }\frac{8}{\sqrt[]{113}\text{ }}\text{ = }\frac{8\sqrt[]{113}}{113}`
`\tan \text{ W = }(8)/(7)`
