First you must know that for remarkable angles: cos (0) = 1, cos (π) = - 1, cos (π / 2) = 0, cos (3π / 2) = 0, cos (2π) = 1. Then, by simple substitution in the given formula, you can find the solutions of x. Which for the interval [0, 2π) are: x = π, x = pi divided by two and x = three pi divided by two.Attached solution.
N=0 is the answer for this problem
Answer:
from that passage AB+BD=AD ; -4x+50+2x+4=2x+46 so -2x+54=2x+46 ; x=2.
AC=AB+BC ; AB=-4x+50=-4(2)+50=42
the total lengths is AD=2x+46=50
Therefore AC is more than 42 and less than 50 ; you can answer b,c,g
The area of the composite shape is the sum of the area of the triangle and the area of the rectangle. The area of the composite shape is 53 in².
<h3>What is Geometry?</h3>
It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The composite is made up of triangles and rectangles.
The area of the composite shape will be the sum of the area of the triangle and the area of the rectangle.
The area of the triangle will be
The area of the rectangle will be
The area of the composite shape is 48 + 5 = 53.
The area of the composite shape is 53 in².

The side lengths are the same.
Step-by-step explanation:
A rigid transformation does not change any dimensions. The side lengths are the same.
