Answer: uhh provide a picture
Step-by-step explanation:
In order to prove the triangle is a right angled triangle we need to prove that the slope of the lines CA and BC and AB have any negative reciprocals.Lets find the slopes .
AB=(-1,3), (1,2) slope of AB = 2-3/1-(-1)= -1/2 slope of AB is -1/2
BC = (1,2), (-3,1) slope of BC is 1-2/-3-1= -1/-4 slope of BC is 1/4
Slope of CA =(-3,1)(-1,3) slope of 3-1/-1-(-3)=-2/-2=1
Since the slopes do not have any negative reciprocals so the triangle is not a right angled triangle

= 105.57
= 105.6 cm²
Number 1.
, first we will take the
of both of these numbers getting us,
, which then gives us that 
Number 2
, solve for our exponent,
, use the logarithmic formula, and we get,
, which then we get that
