Mrs. Williams begins to teach her students about Sine and Cosine Ratios. Amelia is having a lot of fun while Hazel does not understand.
Make sure your calculator is in degree mode. Find the Sine and the Cosine button on your calculator. The formulas are sin (theta)= opposite divided by hypotenuse and cosine (theta)= adjacent divided by hypotenuse of a triangle.
Follow the instructions on the board please.
I do not understand this Mrs. Williams!!
YAYY!!

x
cos= adjacent hypotenuse cos 40= 8 cm x 0.7660 = 8 cm x 0.7660x= 8 cm x= 10 cm
40 degrees
8 cm
40 degrees
Alright here is the solution!
YAYY I got it right!
AW man I will never understand this!
