Answer:
the second one, ((6 x 5) x 4) +((5 x 4) x 2) = 160
the third one, ((7 x 6) x 4) + (6 x 4) x 2) = 216
the fourth one, ((8 x 4) x 4) + ((4 x 3) x 2) = 152

Answer:
(0,-4-4√6) and (0,-4+4√6)
Step-by-step explanation:
To determine the coordinates as Jon wants to place it 14 points away
√10^2+(a+4)^2 = 14
100+(a+4)^2 = 196
(a+4)^2 = 96
a+4 = ±√96
a+4 = ±4√6
a= -4±4√6
Explanation:
Angles 1 & 2 have to equal 180. So, if ∠1 is equal to 140, ∠2 is equal to 40 because 140 + 40 = 180.
So far... we know that:
Angles 2, 9, and 11 make a triangle, a triangles "magic number" is also 180. To get 180, you must add up all of the angles. Well... we don't know ∠11 so to find it, you subtract 40 & 80 from 180. 180 - 80 - 40 = 60.
Answer:
∠2 = 40
∠11 = 60
