Answer:
Step-by-step explanation:
recall law of Sines Sin(A) /a = Sin(B) / b
for this question
F = A = 105 and a = 37
E = B and b = 28
then plug those into our law of Sines equations
Sin(105) / 37 = Sin(B) / 28
0.025846 = Sin(B) / 28
28 * 0.025846 = Sin(B)
0.72369 = Sin(B)
arcSin(0.72369) = arcSin ( Sin ( B ) )
46.3599 = B
E = 46° ( rounded to the nearest degree)
Answer:
x = -1.5 y = 8.25
Step-by-step explanation:
5x + 2y - 5x - 10y = -66
8y = 66
y = 8.25
5x + 2(8.25) = 9
x = -1.5
Answer:
B
Step-by-step explanation:
Look at the X and Y coordinates carefully. X and Y coordinates are swapped and Y coordinate got negative sign.
