17 Find the value of x using Trig. Note: If “x” is on top - multiply; If “x” is on bottom - divide!!Remember: SOH CAH TOATHIS IS JUST THE ANGLE!!Since we have anA & H we use CosCox 62 = 50/xSince we have anO & A we use Tan(no hypotenuse!)Tan 64 = x/7Since we have anO & A we use Tan(no hypotenuse!)Tan 67 = 6/xSince we have anO & H we use SinSin 35 = x/20647X------67x6------35----X206250------xSince x is on top, mult.Type 7 * tan 64 in calc.Since x is on bottom divide.Type 6 divided by tan 67 in calcSince x is on top, mult.Type 20 * sin 35 in calc.Since x is on bottom divideType 50 divided by cos 62in calc.
18 Find the value of x degrees using Trig. Note: When finding an angle measure use “inverse” Trig. or the 2nd button!!Remember: SOH CAH TOASince we have anO & A we use Tan(no hypotenuse!)Tan x = 9/3Since we have anA & H we use CosCos x = 16/20Since we have anO & H we use SinSin x = 4/5x39____x16-----20x____4571.636.953.1Since x is the angle, use the 2nd button!Type 2nd Sin, then 4/5 using the n/d button.Since x is the angle, use the 2nd button!Type 2nd Tan, then 9/3 using the n/d button.Since x is the angle, use the 2nd button!Type 2nd Cos, then 16/20 using the n/d button.
19 What have I learned? SOH CAH TOA If “x” is on bottom “divide” If “x” is on top “multiply”If solving for a side use regular sin, cos, or tanIf solving for an angle use inverse sin, cos, or tan
20 Here’s your daily joke Why didn’t sin and tan go to the party?Just cos Ha! Ha!
