This is Lulu's math hair salon. instead of paying for your haircuts you pay by solving math problems.
Ughh!! Mrs. Karen doesn't know how to teach trigonometry I hope this salon could get me ready for my exam, and make my hair look amazing
Lulu's math Hairsalon
Welcome, how are you? my name is Layan how may I assist you?
I am good thank you for asking. My name is Juju could you please dye my hair pink, I am in 10th grade and I have trouble learning trigonometry
Where would you like to start on the lesson
How about SOH,CAH,TOA.
Okay first you need to need to know the rules: -SOH= sine = opp/hypCAH=cosine= adj/hypTOA=tangent=opp/adjThe second thing you need to know is how the questions will be like:-You will either need to find the trigonometric ratio, find a missing side, Find a missing angle.
Thank you I finally understand the rule could show me how to solve this worksheet?
Write the trigonometric ratio Sin j= opp/hyp= 60/61= 0.9Cos j= adj= 11/61= 0.18Tan j= opp/adj= 60/11=5.4
Find missing angle COS x= 4/5x= COS-1(4/5)x=36.8
What is the value of Y COS(30)/1=9/yY= 9/COS(30)Y= 10.39
Thank you so much Layan I love my hair its soo good and also thank you I am going to ace this exam.
