a)    As we can see that 

                    tan (62 degree) = x / 98        then

                   1.8807 = x / 98

                     x = 1.8807 * 98

                    x = 184.3086 m

b)      As we can see that 

                    sine (48 degree) = 14.3 / x        then

                   0.7431 = 14.3 / x

                     x = 14.3 / 0.7431

                    x = 19.243 m

c)     As we can see that 

                    cos (60 degree) = 35 / x        then

                   0.5 = 35 / x

                     x = 35 / 0.5

                    x = 70 m

d)     As we can see that 

        9.3^2 = 4.3^2 + x^2

        x^2 = 9.3^2 - 4.3^2

        x^2 = 86.49 - 18.49

        x^2 = 68

        √x^2 = √68

        x = 8.246 mm
