Step-by-step explanation:

❍ Given :

  • Ratio of the angles of a quadrilateral is 3:5:9:13

To Find :

  • Angles of the quadrilateral

Solution :

Let the angles be 3x, 5x, 9x and 13x.

Sum of all the angles of a quadrilateral is 360°.

➠ 3x + 5x + 9x + 13x = 360°

➠ 30x = 360°

➠ x = 360/30

➠ x = 12

Value of x is 12.

The angles are :

◘ 3x = 3 × 12 = 36°

◘ 5x = 5 × 12 = 60°

◘ 9x = 9 × 12 = 108°

◘ 13x = 13 × 12 = 156°

The angles of a quadrilateral are 36°, 60°, 108° and 156°.

❍ Verification :

⇛ 36° + 60°+ 108° + 156° = 360°

⇛ 360° = 360°

Hence, Verified.

Answer :

Firstly,

Let,

The angles of quadiarallel will be 3x, 5x, 9x and 13x

and

we know that,

Sum of angles of quadiarallel = 360°

According to the Question :

 \:  \:  \:  \:  \sf \: 3x + 5x + 9x + 13x = 360^{ \circ} \\  \sf \implies \:  \: 30x = 360^{ \circ} \\ \sf \implies \: x = 12^{ \circ} \\   \\  \bf \: now \\ \green \odot \sf \: value \: of \:  \: 3x = 3 \times 12 = 36^{ \circ}  \\  \\  \green \odot\sf \: value \: of \:  \: 5x = 5 \times 12 = 60^{ \circ}  \\  \\  \green \odot\sf \: value \: of \:  \: 9x = 9 \times 12 = 108^{ \circ}  \\  \\  \green \odot\sf \: value \: of \:  \: 13x = 13 \times 12 = 156^{ \circ}  \\    \:

Therefore, the angles are 36°, 60°, 108° and 156° .
