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
(5r - 20)
Step-by-step explanation:
(3r + 14) + (Ar + B) = (8r - 6)
B = -6 - 14 = -20
A = 8 - 3 = 5
place your dots on the grid
for example r would beeee uhm 3 y x 2
