Answer:
x≈12.5
Step-by-step explanation:
angle a=90°,angle b=28°,side c=11
a+b+Y=180°
Using
y=62°
Using the law of sines, we calculate unknown side x
c=11, a/c=sin a°/sin y°
a=c*sin a°/sin y°
a=11*sin 90°/sin 62°=12.46
12.46≈12.5
Sin2x=2sinxcosx, cos2x=1-2sin^2x
sin(2x)+cos(3x)=2sinxcosx+cos(x+2x)
cos(x+2x)=cosx(1-2sin^2(x))-sinx2sinxcosx
sin(2x)+cos(3x)=2sinxcosx(1-sinx)+cosx(1-2sin^2(x))
Arranging from least to greatest the given data for the temperatures for the last nine days of February,
39, 43, 44, 44, 45, 49, 49, 50, 51
The minimum is 39 and the maximum is 51. Then, for the median, the answer would be 45. Dividing the entries by 4. The lower quartile (Q1) is 43. Thus, the answer is letter B.
