4Trigonometric Hand TrickThis hand trick is an easy way to remember the six trigonometric values of specialangles. It’s a lengthy explanation, not once you know this by heart, you can use this trickeasily. All you need is a non-dominant hand.1.Hold out your non-dominant hand.2.Assign the following values to your fingers.If your non-dominant hand is yourIf your non-dominant hand is yourleft hand . . .right hand . . .3.Find a trigonometric value of a special angle.For example,sin30°.4.Fold the finger assigned to that angle.For example, fold your ring finger for30°.5.Remember the following formulas:Bottom fingersrefer to the number of fingers below the finger you’ve folded.Top fingersrefer to the number of fingers above the finger you’ve folded.6.Calculate the values of your trigonometric expressions using the appropriate formula.Examples:a)?𝑖? 30° =√?????? ???????2=ξ12=12b)??? 30° =√??? ???????2=ξ32c)tan 30° =√?????? ???????√??? ???????=ξ1ξ3=ξ1ξ3ξ3ξ3=ξ33TRIGONOMETRIC RATIOS OF ANGLESSinCosTanCscSecCot30°45°60°?𝑖?𝜃 =√?????? ?𝑖?????2??? 𝜃 =√??? ?𝑖?????2???𝜃 =√?????? ?𝑖?????√??? ?𝑖?????

Can you easily find,what RHU is nearest to yourhouse? Can you solve thedistance from RHU I to RHU IIor the distance from RHU II toRHU III? Draw lines connectingthe three RHUs to form a righttriangle. Can you solve theangles formed in each RHU?What’s Newthe
6Real-life Problems Involving Right TrianglesExample 1:The three RHUs in Baliwag, Bulacan are connected by lines that form a right triangle asshown in the figure below. If the lines from RHU I to RHU II and from RHU I to RHU III formsan angle measuring 60° and the distance from RHU I to RHU III is 400 m, what is the distancefrom RHU I to RHU II?
