for the following (c) and( d) GRAPH one period, identify amplitude,period, phase shift and vertical shift of the graph.

(d) y=2sec(1/3 x)

***This is review for a test, your help will be appreciated. Please show me how you got the answers, THANK YOU!!!***

8) from triangle DBC , tan 50 = h/x

h = x*tan 50 --------------------1

from triangle DAC, tan 20 = h / 6+x

h = (6 +x) * tan 20 --------------------------2

from eq, 1&2 x*tan 50 = ( 6+x)* tan 20

x*tan50 = 6*tan20 + x*tan20

1.19 x = 2.18 + 0.36 x

x = 2.62

from eq 1, h = x*tan 50

h = 2.62*tan50 = 3.13
