Answer:
12
Step-by-step explanation:
These 3 angles are equal, so their sides are also. We can set an equation:
5x-22=3x+2=4x-10
We only need to solve one with 2 expressions:
5x-22=3x+2
2x=24
x=12
To check, we can plug 12 back into the equations:
5(12)-22=3(12)+2=4(12)-10
60-22=36+2=48-10
38=38=38
That means 12 must be an answer.
