Answer:
The answer to your question is below
Step-by-step explanation:
43.-
x = [tex]\sqrt{27^{2} + 22^{2}- 2(27)(22)cos 73}[/tex]
x = [tex]\sqrt{865.66}[/tex]
x = 29.42
44.-
x = [tex]\sqrt{10^{2} + 14^{2} -2(10)(14)cos 66}[/tex]
x = [tex]\sqrt{182.11}[/tex]
x = 13.49
45.-
cos x = [tex]\frac{11^{2} - 17^{2} - 10^{2}}{-2(11)(17)}[/tex]
cos x = 0.7166
x = 44.22°
46.-
x = [tex]\sqrt{16^{2} + 12^{2} -2(16)(12)cos75}[/tex]
x = [tex]\sqrt{300.61}[/tex]
x = 17.34
47.-
cos P = [tex]\frac{6^{2} - 13^{2} -11^{2}}{-2(13)(11)}[/tex]
cos P = 0.888
P = 27.36°
sinR/13 = sinP/6
sin R = 13sin27.36/6
sinR = 0.996
R = 84.71°
Q = 180 - 84.71 - 27.36
Q = 67.93°
48.-
D = 180 - 25 - 113
D = 42°
CD = 9Sin113/sin42
CD = 12.38
ED = 9sin25/sin42
ED = 5.68
