Step-by-step explanation:
Hi there!
We are given the line segment, with the end points AB
The coordinates of A are (-5, -4), and the coordinates of B are (-3, 3).
We want to find the midpoint of the line segment AB
The midpoint formula is given as , where
and
are coordinates
We have two coordinates, which is what we need, but let's label their values to avoid any confusion:
Now substitute those values into the formula:
Now simplify the numerator and denominator
Simplify again:
The midpoint is (-4, )
Hope this helps!
Answer:
b = 8
c = 16
Step-by-step explanation:
From the given right triangle,
a = , m(∠B) = 30°
By applying sine rule in the given triangle,
cos(B) =
cos(B) =
cos(30°) =
c = 16
Further we apply tangent rule,
tan(B) =
tan(30°) =
b = 8
