Answer:
x = 6
Step-by-step explanation:
5x = 24 + 6
5x = 30
5x/5 = 30/5
x = 6
Answer:
$44.45
Step-by-step explanation:
Convert 15 2/5% to decimal, =0.154
38.52+(38.52x0.154) (do this to add the cost of the % increase)
≈$44.45.
Answer:
Step-by-step explanation:
Let the missing angle be x then .,
81 + 62 + x = 180 (being sum of angles of triangle )
143 + x = 180
x = 180 - 143
x = 37
<em>Therefore the missing angle is 37</em>
Step-by-step explanation:
1) if (0;0) if point A, (1;2) is point B; (-1;-2) is C, (2;1) is D, then
2) the vector AB is (1;2); vector AC is (-1;-2) and vector AD is (2;1), then
3) the length of AB, AC and AD are:



4) if the lengths above are equal, then it means that (0, 0) is equidistant from (1, 2), (-1, -2) and (2, 1).
