The perimeter of a rectangle is 72 cm. The length is 3 more than twice the width What

solmaris [256]

<h3>Solution</h3>

Given :-

Perimeter of rectangle = 72 cm
The length is 3 more than twice the width.

Find :-

Dimensions of rectangle

<h3 /><h3>Explantion</h3>

Using Formula

$\boxed{\underline{\tt{\red{\:(perimeter_{rectang}\:=\:2\times (Length+Width)}}}}$

Let,

Length of Rectangle = x cm
Breadth of Rectangle = y cm

According to question,

==> perimeter of Rectangle = 72

==> 2(x+y) = 72

==> x + y = 72/2

==> x + y = 36_________________(1)

Again,

==> x = 2y + 3

==> x - 2y = 3__________________(2)

Subtract equ(1) & equ(2)

==> y + 2y = 36 - 3

==> 3y = 33

==> y = 33/3

==> y = 11

keep in equ(1)

==> x - 2×11 = 3

==> x = 3 + 22

==> x = 25

<h3>Hence</h3>

Length of Rectangle = 25 cm
Width of Rectangle = 11 cm

The bearing of Y from X is 63

zimovet [89]

Answer:

117°

Step-by-step explanation:

As per diagram:

∠NXY ≅ ∠XYZ as alternate interior angles since XN and YN are parallel and XY is transversal
m∠XYZ = m∠XZY = 63° since ΔXYZ is isosceles

Find the measure of ∠YXZ:

m∠YXZ = 180° - 2*63° = 54°

Find the bearing of Z from X:

m∠NXZ = m∠NXY + m∠YXZ = 63° + 54° = 117°
