A 11.54 QUESTION 4 Click Save and Submit to save and submit. Click Save All Answers to save all aExplanation / Answer
1) b = 6 , A = 30
C = 90
B = 180 - ( 30 + 90 )
B = 60
applying cosine rule
cos 30 = b / c
cos 30 = 6 / c
c = 6.93
tan 30 = a / b
a = 3.46
option D is correct
2) a = 7 , B = 25
C = 90
A = 180 - ( 90 + 25 )
A = 65
cos 25 = 7 / c
c = 7.72
tan 25 = b/ 7
b = 3.26
option c is correct
3) b= 2 , c = 10
cos A = 2 / 10
A = 78.46
B = 180 - ( 78.46 + 90 )
B = 11.54
a = sqrt ( 10^2 - 2^2 )
a = 9.80
option a is correct
