51.8 cm- width
Answer:
x = 66
y = 68
Step-by-step explanation:
y is the same as the angle that is 68 degrees. Then, because the total of 46, x, and y should = 180, you solve for 180 by plugging in the y value.
46 + x + 68 = 180
114 + x = 180
x = 66
Law of cosines:
b^2 = a^2+c^2 -2*a*c*cos(B)
b^2 = 400^2 + 240^2 - 2*400*240*cos(16)
b^2 = 217600 - 184562.25
b^2 = 33037.75
b = sqrt(33037.75)
b = 181.76 = 181.8 yds.
The answer is D.
Let
x------------> <span>the average yearly temperature
if </span><span>One year was particularly warm, and the average temperature each month increased by 5°
in one year the temperature increased------->5*12-----> 60</span>°<span>
so
[the new </span>average yearly temperature]=x+(60)*12-------> x+5°
therefore
the answer is the option
<span>B) The average increased by 5°. </span>
