Answer:
Thale's theorem stated that if a line parallel to the base of the triangle intersects it, the ratio of sides of the respective sides is equal
In this diagram, since the 2 horizontal lines are parallel
the ratio of the 2 sides on the left and the 2 sides on the right will be equal
Hence,
x/15 = 2/10
x = 30/10
x = 3
12. if you take half of 12, 6, then you add 5, you get 11.
<span>lengths are in ratio 1:3
areas are in ratio
1 : 3</span>²<span> = 1: 9
area of ADG = 9 x 42 = 378 </span>
