Answer:
4. 8.0
5. 27.6
6. 35.5 degrees
Step-by-step explanation:
#4- Cos 48= x/12
0.669131= x/12
x=8.0
#5
Sin 78= 27/x
0.978=27/x
0.978x=27
x=27.6
#5
Tan X= 15/21
tan x= .714
inverse tan= 35.5 degrees
D and e would be the answer
3x + 5x = 320
8x = 320
x = 40
3(40) : 5(40) = 120 : 200
The best answer would be Option C.
Volume = 4/3×pi×r^3
= 4/3×3.14×12^3
= 7234.56
~ 7235
