Answer:
4. 18-(-12)
Step-by-step explanation:
so i basically took 12 and added that to 18 [and got 30] to find out how many degrees it went up and then i solved each equation till i got 30. I hope this helped and that you could understand the way i did it.
The correct answer is D.14.
The interquartile range is the difference between the Upper Quartile and the Lower Quartile of a data set.
By arranging the numbers in the stem and leaf plot from lowest to highest value, you get an even set of data (31,33,35,41,43,46,48,49,49,50). By dividing the set into two, you get a lower half of your data (31,33,35,41,43) and an upper half (46,48,49,49,50). The lower quartile is the median or the midpoint of the lower half of your data while upper quartile is for the upper half. The lower quartiles is 35 and upper quartile is 49. The difference between the two is 14.
<span>So,Given that you have A = 23 degrees , B = 21 degrees ,
and side a = 42.8, we find the angle C and the remaining sides of the triangle to be as follows:
Calculating for C = 180 degrees - ( A + B ).
C = 180 - 44 = 136
a / sin A = b / sin B = c / sin C
b = a sin B/ sin A = 42.8 sin 21 / sin 23 = 39.3
c = a sin C/ sin A = 42.8 sin 136/ sin 23 = 76.1
42.8/sin 23 = 109.5
39.3/sin 21 = 109.7
76.1/sin 136 = 109.6
The correct answer is ( c ). C = 136, b = 39.3 , and c = 76.1.</span>
