Attached is a picture showing the plot in the plane.
Note that for a complex number , x + iy.
The real part of the number is put on the x axis and the imaginary part is put on the y axis.
So plotting:
A = 4 + 1i
B = 9 + 7i
C = 5 + 8i
See picture.
Answer:
no it's an acute triangle
Step-by-step explanation:
why? because any angle below 90 degrees is considered an acute triangle which in your case 20,24, and 36 are all very far from being a right triangle
Answer:
Step-by-step explanation:
There are four points here. We look at the x-values and identify {2, 1, -2, 1]. This can be reduced to {-2, 1, 2}
Unfortunately, the input '1' shows up twice and thus the relation cannot be a function; we cannot have two different y-values for the same x-value (1).
59° + 81°+ x° = 180°
140° + x° = 180°
x = 40°
Answer:
35°
Step-by-step explanation:
Extending line BC to point E on line AD
angle CED = 20° + 95°= 115°
ang|BCD|= ang|CED| + y
150°=115° + y
y= 150° - 115°
y= 35°
