Answer:
x=11
Step-by-step explanation:
For extra help the second answer is: 7a(3-a)
Answer:
x = 5
Step-by-step explanation:
Since both triangles are similar hence;
m<CAB = m<CDE
Given theta
m<CAB = 50degrees
m<CDE = 10x
Substitute the given angles
50 = 10x
Swap
10x = 50
Divide both sides by 10
10x/10 = 50/10
x = 5
Hence the value of x is 5
The answer would look something like this:

There could also have a simplified version.
I hope this helps.
One meter is 3.28 feet, so anything shorter than that. A basketball, maybe a very young child?
