Answer:
27.86 cm
Step-by-step explanation:
use a^2+b^2=c^2
plug in 10 to a and 26 to b
so
10^2+26^2=c^2
then simplify
100+676=c^2
776=c^2
then find the square root of 776 which is 27.856... cm
this can be simplified to 27.86 cm
change it to 28 cm if your teacher wants it rounded to the whole number

Answer: -13, -15
Step-by-step explanation:
If x is the smallest integer, then:
x + (x + 1) + (x + 2) = x - 27
3x + 3 = x - 27
2x = -30
x = -15
Integers: -15, -14, -13
Answer:
20
