Answer:
n+3
Step-by-step explanation:
we have
-3+4i
let magnitude be |z|
|z|=
|z|=5 unit
11. shape 1 => A = ½×17×10=85m²
shape 2=> A = 17×9 =153 m²
total area = 238 m²
12. shape 1 => A = 7×3= 21 m²
shape 2=> A = 3×2 = 6 m²
total area = 27 m²
x = 15
The sum of the angles in a triangle is 180º
3x + 5x + 4x = 180
Combine like terms
12x = 180
Divide both sides by 12
C = 5x
C = 5 * 15
C = 75º
