An angle bisector of a triangle divides the opposite side of the triangle into segments 5 cm and 3 cm long. A second side of the
attashe74 [19]
There is a little-known theorem to solve this problem.

The theorem says that
In a triangle, the angle bisector cuts the opposite side into two segments in the ratio of the respective sides lengths.

See the attached triangles for cases 1 and 2.  Let x be the length of the third side.

Case 1:
Segment 5cm is adjacent to the 7.6cm side, then
x/7.6=3/5  => x=7.6*3/5=4.56 cm

Case 2:
Segment 3cm is adjacent to the 7.6 cm side, then
x/7.6=5/3 => x=7.6*5/3=12.67 cm

The theorem can be proved by considering the sine rule on the adjacent triangles ADC and BDC with the common side CD and equal angles ACD and DCB.

What is the surface area of the net of the rectangular prism?
swat32

Answer:

638.32 yd²

Step-by-step explanation:

The surface area of any figure can be found by calculating the area of all the sides and finding the sum.  In a rectangular pyramid, there is a rectangular base (l x w) and the same two triangles on one side and another two identical triangles on the other side.

Area of rectangle: A = l x w

Area of a triangle:  A = 1/2(b)(h)

Rectangle: 16 x 13.4 = 214.4 yd²

Bottom/top triangles: 14.1 x 16 = 225.6 yd²

Side triangles: 14.8 x 13.4 = 198.32 yd²

Total:  198.32 + 225.6 + 214.4 = 638.32 yd²
