Question

PLEASE HELP!!!

Find sin D, sin E, cos D, and cos E. Write each answer as a fraction in simplest form.

Answer 1

sin D = FE/DE = 13√3 /26 = √3 /2

sin E = DF/DE = 13/26 = ½

(sin E = cos D)

cos D = DF/DE = 13/26 = ½

cos E = EF/DE = 13√3 /26 = √3 /2

(sin D = cos E)

Answer 2

Here are what they equal in their simplest forms!

Explanation:

Sin D & Cos E were originally equal to 13 -/3 over 26

-

Sin E & Cos D were originally equal to 13/26
