Answer:
Pepper Jackie still has 5.8
Step-by-step explanation:
If this is a english problem instead of a math problem to correct the sentence it would be Pepper Jackie has 5.8
Note that
108° = 90° + 18°
so
sin(108°) = sin(90° + 18°) = sin(90°) cos(18°) + cos(90°) sin(18°) = cos(18°)
Then
sin²(108°) + sin²(18°) = cos²(18°) + sin²(18°) = 1
by the Pythagorean identity.
A= (a+b+c)h is the formula. I hope this is helpful for you. I am pretty positive it will help.
