C
a ratio of 5 : 5 simplifies to 1 : 1, which basically means we require the midpoint of the line segment
using the midpoint formula
M = [ (0 + 20 ), (15 + 0)] = (10, 7.5 )
A+bi is the form of a complex number. a is on the x axis, bi is on the y axis:
3-4i ( x positive, y negative) Q4
-1-3i (both x, y negative) Q3
4+i ( both x, y positive) Q1
-2+2i (x neg, y pos) Q3
First. we use the Pythagorean theorem:
Add the numbers in

So, the leg has a length of 40 mm.
Answer:
g = 118°, h = 62°, k = 140°, m = 40°
Step-by-step explanation:
g = 118°
h = 180 - 118 = 62°
k = 140°
m = 180 - 140 = 40°
