F(x)=x-5
f(4)=x-5
f(4)=4-5
f(4)=-1
This kind of triangle is acute triangle because on the given three angles, none of them does not exceed more than 90°.
Step-by-step explanation:
Given points are (-2,5) and (3,-17)
to find midpoint, use this formula
( x1+x2/2 , y1+y2/2)
where points are a(x1,y1) and b(x2,y2)
coming to the question,
midpoint is :
[ (-2-3)/2 , (5-17)/2 ]
[ -5/2 , -12/2 ]
[ -2.5 , -6 ]
