Answer:
x = 4
Step-by-step explanation:
note the exact value of tan60° = 
Since the triangle is right use the tangent ratio to find x
tan60° =
= 
multiply both sides by x
x ×
= 4
divide both sides by 
x =
= 4 ×
= 4
The median of a set of data is obtained by arranging the data from lowest to highest. In this pop quiz scores, the arrangements is as follows:
110, 125, 138, 144, 152, 153, 162, 163, 164, 174, 174, 175, 177, 180, 183, 185, 186, 187, 194, 195, 196, 198.
There are 22 items in the list and the median is located in the middle position. In this case, it is the average of 174 (11th) and 175 (12th). Thus, the median is 174.5.
X=16
y= -12
X+2( -x+4)=-8
X-2x+8=-8
-1x=-16
X=16
Y=-16+4
Y=-12
The answer is B, because if you draw the baseboards on the scale drawing, you'll get nineteen baseboards. 19 x 4,19 = 79,61
