On the coordinate grid of a map. Jeff's house is located at (9,5). Hannah's house is at (-5,-5). Kenya's house is located at the
Andru [333]
The midpoint formula is \frac{ x_{1} +  x_{2} }{2},  \frac{ y_{1}+ y_{2}  }{2}
So just plug in the corresponding coordinates in the correct place to get the midpoint.
x_1=-5 ; x_2=9 ;  y_1=-5 ; y_2=5
((-5 + 9)/2 , (-5 + 5)/2)
(4/2 , 0/2)
(2,0) is where Kenya's house is(which is the midpoint). 

The distance formula is a bit more complicated than that. The distance formula is D=\sqrt{({y_{2}- y_{1} }^{2})  + ({ x_{2}- x_{1}}^{2} )  }
In this case now, your looking for the distance from Hannah's house to Kenya's house.
D=\sqrt{(-5-2)^{2} + (-5-0)^{2}  }
=\sqrt{49+25}
=\sqrt{74} ≈8.6023

labwork [276]

here is your answer mate.

in triangle ABC

angle ABC + angleBAC + angleACB = 180 Degrees. (angle sum property of triangle)

90 + 58 + angle ACB = 180 degree.

148 + angle ACB = 180 degree.

angle ACB = 180 - 148

angle ACB = 32 degree

the angle of elevation is 32 degrees
