Answer:
4.9
Step-by-step explanation:
First set up the equation:
Then substitute in known values:
and solve for C
(a)7x4=28
2x2=4
28-4=24
24-1=23 points
(b)20/4=7 correct answers
Answer:
take 42 degree as reference angle
using sine rule
sin 42=opposite/hypotenuse
0.66=x/23
23*0.66=x
15.18=x
15.2=x
take x degree as reference angle
using cos rule
cosx=adjacent/hypotenuse
cosx=29/42
cosx=0.69
cos 46 =0.69
therefore x=46 degree
