Answer:
the best approximation is 2√35
Step-by-step explanation:
We have
SinC/ c = Sin A / a
Sin 71/ 26 = Sin A / 27
Sin A = 27 Sin 71 / 26 = about .982
So°
Sin-1(.982) = A = 79. 08°
Then angle B = 180 - 71 - 79.08 = 29.92°
And b is given by
b/sin29.92 = 26/sin 71
b = 26sin29.92/sin71 = about 13.72
But A could also be an obtuse angle = 180 - 79.08 = 100.92°
So we have
B = 180 - 71 - 100.92 = 8.08°
And we have
b / sin 8.08 = 26/sin71
b = 26sin8.08/sin 71 = 3.865
[(14,7 + 5,9) x 5,8] / 2 = 59,74 cm^2
I'm not sure what the answer can be for this
Answer:
The coordinates of point B are (-3,-3).
Step-by-step explanation:
Let 
, 
and 
, then we have the following formula by vectorial definition of a line segment:
![B(x,y) -A(x,y) = \frac{3}{4}\cdot [C(x,y)-A(x,y)]](https://tex.z-dn.net/?f=B%28x%2Cy%29%20-A%28x%2Cy%29%20%3D%20%5Cfrac%7B3%7D%7B4%7D%5Ccdot%20%5BC%28x%2Cy%29-A%28x%2Cy%29%5D)
