5 - X - X = -1
5 - 2x = -1
-2x = -1 - 5
-2x = -6
X = 3.
This is the formula c=a2+b2
The area is 1,665 inches squared.
Answer:
Given:-Point P is the mid -point of MN and C is mid point of MP.
To prove:-MC =1/2PN
Proof:- As P is the mid -point of MN then P divides MN into two equal halves
such that MP=1/2MN=PN ....................(1).(by Euclid's axiom "things which are equal to the same thing are also equal to one another")
Similarly as C is the mid point of MP then MC=1/2MP=CP ................(2)
Now replacing MP by PN from (1)in (2),we get
MC=1/2(PN)...................hence proved.
X^2 = 7^2 - 3^2
