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

<span>y" + 9y = 0
m^2 + 9 = 0
m = ± 3i
yH = C1 cos 3t + C2 sin 3t
yP = C3 t sin 3t + C4 t cos 3t
