Answer:
No
Step-by-step explanation:
Can a triangle with the following sides exist? 7, 8, 1
Answer is NO
Because the sum of any two sides has to be greater than the third side but here we have:
M/(30-15) = m/(30+15) + 1
m/15 = m/45 + 1
45*m/15 = 45*(m/45 + 1
3m = 45*(m/45) + 45*(1)
3m = m+45
3m-m = m+45-m
2m = 45
2m/2 = 45/2
m = 45/2
m=22.5
