Answer:
144
Step-by-step explanation:
Sum of interior angles:
180(n-2)
180(10-2)
1440
Measure of each interior angle:
1440/10=144
I’m pretty sure there are infinite solutions as the system of equations are equivalent to each other.

Answer:
6.9
Step-by-step explanation:
Use the Pythagorean theorem :
a^2 + b^2 = c^2
so,
11^2 + b^2 = 13^2
121 + b^2 = 169
b^2= 48
b = 6.928
Round to the tenth : 6.9
