Answer:
33×33+33-33÷0=infinity
33×33=1089
33-33=0
Taking L.H.S
=33×33+(33-33)÷0
=1089+0÷0
=1089÷0
=infinity
L.H.S=R.H.S

Answer:
60
Step-by-step explanation:
perimeter (p) = 8 + 17 + 15 = 40
semi-perimeter (s) = p/2 = 20
Area = square root of s(s-a)(s-b)(s-c) where a,b,c are the sides of the triange by Herons formula.
Therefore, area = 20(20-8)(20-15)(20-17) = square root of 3600 = 60
