Question

Part 2 of me forgetting everything

Answer 1

Answer:

x = 15

Step-by-step explanation:

There are 2 triangles. The small triangle CDE has sides that are 8 and 20.

The big triangle CAB has sides 6+8 and 20 + x. Add the 6 and 8 which is 14. Create a proportion and cross multiply, divide, then solve for x.

$\frac{8}{20}=\frac{14}{20+x\\}\\\\8(20 + x) = 20(14)\\160 + 8x = 280\\160-160+8x=280-160\\8x= 120\\8x/8=120/8\\x=15$
