Answer 1

Answer:

8x+4x+3x+3x=360

18x=360

x=20

Angles are- 160,80,60,60

Answer 2

Answer:

Angles are 80°, 40°, 60°, and 60°

Step-by-step explanation:

Let the angles be 8x, 4x, 3x, and 3x

By angle sum property,

$\implies \: 8x + 4x + 3x + 3x = 360^{ \circ}$

$\implies \: 18x = 360^{ \circ}$

$\implies \: x = \dfrac{360^{ \circ} }{18 \: }$

$\implies \: x = {20}^{ \circ}$

The angles are,

• 8x = 8(20) = 160°
• 4x = 4(20) = 80°
• 3x = 3(20) = 60° each.

Note:

In a quadrilateral the sum of all interior angles are 360° and is called as angle sum property.
