Answer:
mAB = 49
mABC = 253
mBAC= 156
mACB = 311
Step-by-step explanation:
If a line <span>parallel </span>to one side of a <span>triangle </span>intersects the other two sides of the triangle, then the line divides these two sides proportionally.
For letter b:
First times 5 on both sides to get rid of the denominator of 5
5 * y
— = 4 * 5
5
Then the answer is
y = 20
For letter c:
First move constants on one side, variables on the other
2g = 17 - 8
Then collect like terms:
2g = 9
Then divide both sides which would equal:
g = 9/2
For example, three points are always coplanar, and if the points are distinct and non-collinear, the plane they determine is unique. However, a set of four or more distinct points will, in general, not lie in a single plane. Two lines in three-dimensional space are coplanar if there is a plane that includes them both.
