Answer:
1) 5.20 if rounded
2) 123.04 if rounded
3) 16.17 if rounded
Step-by-step explanation:
1) tan (30) = x/9
x = tan (30) (9)
x = 5.1961... (5.20 if rounded)
2) sin (25) = 52/x
x = 52/sin(25)
x = 123.0424... (123.04 if rounded)
3) cos (18) = x/17
x = cos (18) (17)
x = 16.1679... (16.17 if rounded)
hope it helps
