Part 2 of me forgetting everything

Mathematics
1 answer:
Lunna [17]3 years ago

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

Answer:

x = 15

Explanation:

First, add both equations on one side, and set it equal to 180° because it's supplementary:

2x + 8 + 8x + 22 = 180

combine like terms:

10x + 30 = 180

subtract 30 on both sides of the equation and you end up with:

10x = 150

divide both sides by 10 and you get:

x = 15
