Step-by-step explanation:
(a) 25/400 X 3,875 = $242.19
(b) 50/300 X 96 = 16 lamps
(c) 175/200 X 540.72 = 473.13
(d) 100/300 X 750 = 250 boys
(e) 133/200 X240= 159.6
We know that
applying the law of sines
50/sin 40=60/sin x
50*sin x=60*sin 40
sin x=[60*sin 40]/50
sin x=0.7713
x=arc sin (0.7713)----> x=50.47°--------> x=50.5°
the answer is
x=50.5 °
