Hence, The value of x in the congruent triangles abc and dec is 1
<h2>What is geometry?</h2>
the branch of mathematics concerned with the properties and relations of points, lines, surfaces, solids, and higher dimensional analogs.
<h3>How to solve?</h3>
The question implies that the triangles abc and dec are congruent triangles.
The congruent sides are,
ab = de
bc = ce = 4
ac = cd = 5
The congruent side ab = de implies that,
4x - 1 = x + 2
Collect like terms,
4x - x = 2 + 1
Evaluate the like terms,
3x = 3
Divide through by 3
x = 1
Hence, the value of x is 1

Answer:
Option (3).
Step-by-step explanation:
Option (1).
Since measure of an inscribed angle =
m∠ABC =
= 2(m∠ABC)
= 2(30°)
= 60°
Therefore, this option is not true.
Option (2),
Since,
m(arc AB) = 360 - 220
= 140°
Therefore, this option is not correct.
Option (3),
= 60° + 160°
= 220°
Option (3) is the correct option.
Option (4),
= 360° - 60°
= 300°
Therefore, this option is not correct.

Answer: Parallelogram</h3>
You could use the parallelogram rule to add the vectors, or you could use the tip-to-tail method (your textbook might call it the "head to tail method" but it's the same idea).
An example of the parallelogram method is shown below with adding the vector u = (-4,4) in red to the vector v = (8,2) in blue to get the vector w = (4,6) in green. The green resultant vector is one of the diagonals of the parallelogram
Side note: The other diagonal is either u-v or v-u depending on your reference point.
