25. x = 5.5
26. x = 10.4
27. x = 19.2
28. x = 38.1
Explanations:
(Since all the triangles are right triangles, we can use trigonometry to find x.
sin = Opposite/Hypotenuse
cos = Adjacent/Hypotenuse
tan = Opposite/Adjacent)
25:
cos(67) = x/14
cos(67) * 14 = x
x = 5.5
26:
sin(48) = x/14
sin(48) * 14 = x
x = 10.4
27:
tan(32) = 12/x
x = 12 / tan(32)
x = 19.2
28:
sin(41) = 25/x
x = 25 / sin(41)
x = 38.1
