For y try substracting 112 from 180 wich should give u 60 which is y now add 60 plus 58 which is 118 now substract 118 from 180 which is 62 aka x
The mid-point is basically the average of the coordinates. So for the x coordinate do (1+(-7))/2=-3. and for y, do (-10+7)/2=-3/2
This gives you the midpoint as (-3,-3/2)
The answer is 44.
40 / 100 = 0,4 * 10 = 4 (10%)
40 + 4 = 44
The gaps in the area needs to be closed so the data you use is lenient
Answer:
E
Step-by-step explanation:
The problem says that triangle BDC lies in the plane k, which means that whatever angle is formed by another point beyond this plane with any of the three segments that form BDC (BD, DC, and BC) is the same as the angle formed by the line connecting the point and the plane.
Here, we're given that AD⊥DC, which means AD forms a 90° angle with DC. Then, since DC is already on the plane, we already know for sure that AD is definitely perpendicular to plane k.
Thus, the answer is E (none of these).
