Question

URGENT!!!

Which is equal to sin of angle e?
a) cos of angle D
b) cos of angle F
c) sin of angle D
d) sin of angle F

Answer 1

B) cos f

Explanation:

sin e = DF/EF

cos d = (which side is adjacent i don't even know)/EF

cos f = DF/EF

sin d = opposite (hypotenuse)/hypotenuse, doesn't make sense

sin f = DE/EF

life lesson in trig: don't try to do right triangle trig using the right angle, it won't work out
