Question

Please help I don't understand!

Answer 1

Answer: SAS similarity theorem

Build proportional relation:

`\Rightarrow \sf (AC)/(BC) = (EC)/(DC)`

`\Rightarrow \sf (200)/(150) = (320)/(240)`

`\Rightarrow \sf (4)/(3) = (4)/(3)`

• So, the given that two sides are congruent and one angle equal.
